abstract = {Algorithms incorporating learned functionality play an increasingly important role for highly automated vehicles. Their impressive performance within environmental perception and other tasks central to automated driving comes at the price of a hitherto unsolved functional verification problem within safety analysis. We propose to combine statistical guarantee statements about the generalisation ability of learning algorithms with the functional architecture as well as constraints about the dynamics and ontology of the physical world, yielding an integrated formulation of the safety verification problem of functional architectures comprising artificial intelligence components. Its formulation as a probabilistic constraint system enables calculation of low risk manoeuvres. We illustrate the proposed scheme on a simple automotive scenario featuring unreliable environmental perception.} }

Such models can, in contrast to purely functional controller models, not be analyzed with hybrid verification engines relying on explicit representations of modes, but require fully symbolic representations for both the continuous and discrete part of the state space. The presented abstraction methods directly work on a symbolic representation of arbitrary nonconvex combinations of linear constraints and boolean variables using LinAIGs. Several interpolation methods allow us to compute abstractions consisting of fewer linear constraints, and hence reduce the complexity of the reachable state set computation. In combination with methods that guarantee the preciseness of abstractions, this leads to a significant reduction of the runtimes of the verification process compared with exact verification.},

Such models can  in contrast to purely functional controller models  not analyzed with hybrid verification engines relying on explicit representations of modes, but require fully symbolic representations for both the continuous and discrete part of the state space. The optimization techniques shown yield consistently a speedup of about 20 against previously published results for a similar benchmark suite, and complement these with new results on counterexample guided abstraction refinement. In combination with the methods guaranteeing preciseness of abstractions, this allows to significantly extend the class of models for which safety can be established, covering in particular models with 23 continuous variables and 2 to the 71 discrete states, 20 continuous variables and 2 to the 199 discrete states, and 9 continuous variables and 2 to the 271 discrete states.},

abstract = {Industrial applications usually require safety and stability properties. The safety property guarantees that "something bad" never happens, and the stability property guarantees that "something good" eventually happens. The analyses of both properties are usually performed in isolation. In this work, we consider analyzing both properties by a single automatic approach for hybrid systems. We basically merge analyses of both properties to exploit the knowledge gained from the analysis of each of them in the analysis of the other. We show how both analyses can be divided into multiple steps and interlocked such that both benefit from each other. In fact, we compute singlemode Lyapunov functions, unroll the hybrid system's automaton via repeated reachability queries, and, finally, compute a global Lyapunov function. Each reachability query is simplified by exploiting the knowledge gained from the singlemode Lyapunov functions. The final computation of the global Lyapunov function is simplified by a precise characterization of the reachable states and reuses the singlemode Lyapunov functions. We provide automated tools necessary to link the analyses and report on promising experiments we performed using our new prototype tool.},

abstract = {We present a projective generalization of closed sets, called complete projective embeddings, which allows us to inscribe Hpolyhedra in quadrics efficiently. Essentially, the complete projective embedding of a closed convex set $P \subseteq K^d$ is a double cone in $K^{d+1}$. We show that complete projective embeddings of polyhedral sets are of particular interest and already occurred in the theory of linear fractional programming. Our approach works as follows: By projective principal axis transformation the quadric is converted to a hyperboloid and then approximated by an inner (right) spherical cylinder. Now, given an inscribed Hpolytope of the spherical cross section, cylindrification of the polyhedron yields an inscribed Hpolyhedron of the spherical cylinder and, hence, of the hyperboloid. After application of the inverse base transformation this approach finally yields an inscribed set of the quadric. The crucial task of this procedure is to find an appropriate generalization of closed sets, which is closed under the involved projective transformations and allows us to recover the nonprojective equivalents to the inscribed sets obtained by our approach. It turns out that complete projective embeddings are the requested generalizations.},

abstract = {Faultinjection is a commonly used method for testing safetyrelevant embedded systems. Especially after the introduction of the ISO 26262 the importance of this technique has gained attention in the automotive domain to test the proper implementation of safety concepts. To enable meaningful tests, the possible random hardware faults need to be aligned in early stages of the development process between the hardware and software developers. Since it is difficult to reason that a system nominal behavior is not affected by the injected faultcode, we aim at an automatic injection of faults into the software units using an AUTOSAR toolchain. An extension in the AUTOSAR design tool is proposed in order to capture fault definitions that shall be used to automatically create triggerable defects in the behavioral models designed with SIMULINK/Targetlink. As first results, it is demonstrated how to integrate faults in Targetlink to be able to use AUTOSAR simulation environments without any further changes to perform faultinjection tests. Furthermore, automatically generated testvectors from requirements are used to trigger the fault injection at runnable level.} }

Our assistance system has to accomplish a comfortable centrifugal force, lane keeping and velocity control. This leads to an architecture composed of a velocity controller and a steering controller, where each controller has its local objectives and together they maintain a global objective. The steering controller makes time bounded promises about its steering, which the velocity controller uses for optimization. For this system, we deductively prove from the components' properties that the objectives of the composed system are accomplished.} }

Considering only critical instances, as analytic approaches do, may deliver pessimistic results leading to higher production costs. In previous works we introduced a statebased approach to validate taskand endtoend deadlines for distributed systems. To improve scalability and reduce the analysis time, the approach computes the state spaces of the individual resources in a compositional fashion. For this, abstraction and composition operations were defined to remove those parts of the inputs of resources which have no influence on the response times of the allocated tasks. In this work, a new abstraction technique is introduced for scenarios where event bursts occur. Further, we extend our approach for systems with cyclic dependencies among the resources. We evaluate our approach on a set of example scenarios and compare the results with the stateoftheart tool Uppaal.} }

For this, abstraction and composition operations were defined to adequately handle task and resource dependencies. During the design process of a system changes occur typically on both the specification and implementation level, such that already performed analyses of the system have to be repeated. In this work, we define a methodology to adequately handle such changes and to determine the minimal part of the affected architecture. For this, we define an appropriate refinement relation between state spaces of the resources.We use contracts to further reduce the revalidation effort. This check takes place at a higher design level, where only the specification is considered.} }

The goal of this work is to integrate the security constraint in an automated DSE process to obtain an architecture which is both costoptimized and secure. In specific, for a given system, our approach defines a formal notion of security, which along with other parameters is fed as an input to the DSE process to obtain an architecture satisfying the defined security and realtime requirements.

It is thus important to have rigorous analysis techniques for determining timing properties of such systems. We consider a layered design process, where timing analysis applies when the system is integrated on a target platform. More precisely, we focus on contractbased design, and ask whether a set of realtime components continues to comply to a given system specification when it is integrated on a common hardware. We present an approach for compositional timing analysis, and define conditions under which the system integration will preserve all the timing properties given by the system specification. Therefore, engineers can negotiate specifications of the individual components a priori, knowing that no integration issues will occur due to shared resource usage. The approach exploits $\omega$languages, which enables analysis techniques based on modelchecking. Such an analysis is shown by a case study.} }

Abstract = {This work is settled in the area of safetycritical embedded systems and presents a formally funded approach for automatically creating an optimized task structure from a Simulink model. Based on an extended task network formalism, in a first step, a formal translation scheme on Simulink block level is defined. Because the resulting tasks are very finegrained and unbalanced with respect to their required computation demand (denoted as task weight), in a second step, an optimized task structure is created by formally merging tasks with each other. Here, the optimization goal is to minimize intertask communication and to balance the weights of tasks. Additionally, it is formally proven that both the translation and the merging of tasks preserves the formal execution semantics of Simulink. The whole approach was implemented as an automated toolchain and evaluated with the help of a case study.},

Abstract = {With a rise in the deployment of electronics in today's systems especially in automobiles, the task of securing them against various attacks has become a major challenge. In particular, the most vulnerable points are: (i) communication paths between the Electronic Control Units (ECUs) and between sensors & actuators and the ECU, (ii) remote software updates from the manufacturer and the infield system. However, when including additional mechanisms to secure such systems, especially realtime systems, there will be a major impact on the realtime properties and on the overall performance of the system. Therefore, the goal of this work is to deploy a minimal security module in a target realtime system and to analyze its impact on the aforementioned properties of the system, while achieving the goals of secure communication and authentic system update. From this analysis, it has been observed that, with the integration of such a security module into the ECU, the response time of the system is strictly dependent on the utilized communication interface between the ECU processor and the security module. The analysis is performed utilizing the security module operating at different frequencies and communicating over two different interfaces i.e., LowPinCount (LPC) bus and MemoryMapped I/O (MMIO) method.},

Abstract = {For most embedded safetycritical systems not only the functional correctness is of importance, but they must provide their services also in a timely manner. Therefore, it is important to have rigorous analysis techniques for determining timing properties of such systems. The ever increasing complexity of such realtime systems calls for compositional analysis techniques, where timing properties of local systems are composed to infer timing properties of the overall system. In analytical timing analysis approaches the dynamic timing behavior of a system is characterized by mathematical formulas abstracting from the statedependent behavior of the system. While these approaches scale well and also support compositional reasoning, the results often exhibit large overapproximations. Our approach for compositional timing analysis is based on ωregular languages, which can be employed in automatabased modelchecking frameworks. To tackle the scalability problem due to statespace explosion, we present a technique to abstract an application by means of its resource demands. The technique allows to carry out an analysis independently for each application that shall be deployed on the same platform using its granted resource supply. Integration of the applications on the platform can then be analyzed based on the different resource supplies without considering details of the applications.},

Abstract = {Conventionally, automotive embedded systems are assessed for evaluating various different aspects such as safety, functionality, and realtime. However, the inclusion of security aspect, which indeed is becoming increasingly important in modern day cars, has a significant impact on the above aspects, especially on functionality and realtime. This impact would be clearly visible in the functional model of the embedded system because including security features modifies the data flow in the system. Thus, the goal of this contribution is to assess and evaluate the security aspect in such systems by exploiting their functional models. Such an assessment further results in establishing a possible relation between realtime formal analysis and the existing security theory. For this, a formal approach},

Abstract = {The effort for the development of a safetycritical embedded system can be reduced tremendously if a similar existing system is used as basis which is then extended by additional functionality. However, this is a very challenging task because in general for both the already integrated and the new parts of such a system complex constraints have to be satisfied to guarantee their correct functionality. Furthermore, larger embedded systems are typically realized as distributed systems with multiple processors connected by a complex communication infrastructure. This leads to a huge number of design alternatives suitable for the extension of such a system thus complicating the manual search for costefficient solutions or even rendering it impossible. Searching entirely automatically is not too promising as well because usually lots of informal requirements have to be satisfied, some of which are concretized while already searching for possible solutions. In this work a semiautomatic approach for the optimization of hardware architectures of embedded systems is presented that supports developers in extending existing systems by adding additional functionality implemented as software tasks. The twotier optimization process explores the design space defined by constraints for valid allocations of the software tasks to the hardware architecture. If necessary, existing processors can be replaced by more powerful ones or additional processors can be integrated while aiming for a costefficient hardware architecture. The optimization approach exploits that larger embedded systems typically use a hierarchical structure where the hardware architecture is composed from hardware subsystems: Firstly, a global (systemwide) optimization step computes preallocations of all additional software tasks onto subsystems based on an abstract characterization of the required and provided computation capacity. Separately for each subsystem, the preallocated tasks are then allocated to processors by local optimization steps under consideration of all subsystemspecific constraints. Software tasks that could not be allocated are handed back to the global tier for being allocated in later iterations. Exact optimization methods are presented for both the global and the local optimization steps. Finally, the results of an extensive evaluation based on three benchmarks are presented. In this evaluation both optimization methods have been compared with alternative approaches.},

month = nov, abstract = {{Systems design has become a key challenge and differentiating factor over the last decades for system companies. Aircrafts, trains, cars, plants, distributed telecommunication military or health care systems, and more, involve systems design as a critical step. Complexity has caused system design times and costs to go severely over budget so as to threaten the health of entire industrial sectors. Heuristic methods and standard practices do not seem to scale with complexity so that novel design methods and tools based on a strong theoretical foundation are sorely needed. Modelbased design as well as other methodologies such as layered and compositional design have been used recently but a unified intellectual framework with a complete design flow supported by formal tools is still lacking albeit some attempts at this framework such as Platformbased Design have been successfully deployed. Recently an "orthogonal" approach has been proposed that can be applied to all methodologies proposed thus far to provide a rigorous scaffolding for verification, analysis and abstraction/refinement: contractbased design. Several results have been obtained in this domain but a unified treatment of the topic that can help in putting contractbased design in perspective is still missing. This paper intends to provide such treatment where contracts are precisely defined and characterized so that they can be used in design methodologies such as the ones mentioned above with no ambiguity. In addition, the paper provides an important link between interfaces and contracts to show similarities and correspondences. Examples of the use of contracts in design are provided as well as in depth analysis of existing literature.}},

abstract = {Today’s and, even more so, the future development of embedded systems faces a variety of challenges. Key success factors to meeting these challenges are suitable concepts for abstraction and structure at different levels of granularity. The result of these concepts is a seamless development approach that heavily facilitates reuse and automation. A basic requirement for such a seamless approach is a clear notion of a system that is formalized by a comprehensive modeling theory. According to this modeling theory, a modeling framework has to provide appropriate models and description techniques for modeling the different aspects and artifacts of system development. This section explains these conclusions and introduces the idea of system and the modeling framework. It also references the modeling theories used in SPES.},

abstract = {Realtime scheduling theory is a powerful technique for efficient analysis of system behaviour. Task Networks as common formalisms for scheduling analysis however often lack expressive power to model functional behaviour like for example different modes of operation. Research focuses on combining different formalisms to raise the expressiveness while maintaining efficient realtime analysis methods. There are rare approaches to extend task network formalisms itself. Though, this would allow a tight integration of scheduling analysis and other verification techniques. Realtime scheduling analysis however heavily relies on decidability of boundedness for executions, and this is not necessarily ensured for more complex formalisms. We discuss such an extended formalism able to model complex realtime systems, and we show that boundedness is still decidable here.},

Here both the discrete part and the continuous part of the hybrid state space are represented by one symbolic representation called LinAIGs. LinAIGs represent (possibly nonconvex) polyhedra extended by boolean variables. Key components of our method for state space traversal are redundancy elimination and constraint minimization: Redundancy elimination eliminates socalled redundant linear constraints from LinAIG representations by a suitable exploitation of the capabilities of SMT (Satisfiability Modulo Theories) solvers. Constraint minimization optimizes polyhedra by exploiting the fact that states already reached in previous steps can be interpreted as 'don't cares' in the current step. Experimental results (including comparisons to the stateoftheart model checkers PHAVer and RED) demonstrate the advantages of our approach.},

We address the quest for optimal models in light of industrial practices in systems engineering, where the development of control strategies is based on combined models of a system and its environment. We introduce the notion of remorsefree dominance between strategies, where one strategy is preferred over another if it outperforms the other strategy in comparable situations, even if neither strategy is guaranteed to achieve all objectives. We call a world model optimal if it is sufficiently precise to allow for a remorsefree dominating strategy that is guaranteed to remain dominant even if the world model is refined. We present algorithms for the automatic verification and synthesis of dominant strategies, based on tree automata constructions from reactive synthesis.},

Properties with exhaustive entry states are restricted to runs originating in a (specified) inner envelope of some modeinvariant. Deciding whether an LHA is reasonable is shown to be decidable in polynomial time. },

abstract = { Specifications and implementations of complex physical systems tend to differ as low level effects such as sampling are often ignored when high level models are created. Thus, the low level models are often not exact refinements of the high level specification. However, they are similar to those. To bridge the gap between those models, we study robust simulation relations for hybrid systems. In this paper, we identify a family of robust simulation relations that allow for certain bounded deviations in the behavior of a system specification and its implementation in both values of the system variables and timings. We show that for this relaxed version of simulation a broad class of logical properties is preserved. The question whether two systems are in simulation relation can be reduced to a reach avoid problem for hybrid games. We provide a sufficient condition under which a winning strategy for these games exists.},

abstract = {Formalisation and verification of requirements is an inevitable task in safetycritical system design. Requirements on networks of timed automata comprise statements about the existence, timeliness, and order of interautomaton communication, possibly also referring to values of variables and clocks. A natural formalism to capture such requirements is the Live Sequence Charts (LSC) language, which in particular has means to refer to dense time. In this work, we provide an observer based modelchecking procedure for the practically relevant fragment of the LSC language in terms of timed automaton semantics of the verification tool Uppaal. Our approach uses the standard LSC semantics defined in terms of the socalled unwinding structure. We show that LSC verification reduces to deadlock or leadsto verification as supported by Uppaal, thereby obtain observer based LSC verification for safety and liveness properties. },

Since Uppaal is known as an efficient tool for model checking of timed automata based systems, it has received much attention. Recently, the class of properties verifiable with Uppaal's reachability checking capabilities has been characterized by a specification logic. In this article we provide a timed languagebased characterization of the same class. Moreover, we show that there is a proper superset of additional (liveness) properties that can be checked by using the features of Uppaal. We characterize also these properties as a class of timed languages. },

In this report we present a model for a lane change assistance system which is meant to serve as a foundation for benchmarks boosting theoretic and algorithmic advances in formal verification of the challenging class of cyberphysical systems. The assistance system implements an autonomous lane change manoeuvre conducted in cooperation with other communicating agents. The model implements a layered design for traffic agents where aspects of communication and autonomous control are described as realtime and hybrid systems, respectively, which are intertwined by synchronous message passing. },

A major difﬁculty for such analytical models in practical usecases is the nontrivial representation of a real implementation model. To overcome this limitation we propose a formal mapping of a concurrent, objectoriented, executable implementation model with explicit shared resources to a realtime task network with functional extensions. The mapping starts from a C++ subset and maps the functional behaviour based on externally observable synchronisation events. The proposed mapping allows to check the implementation model against functional and temporal requirements, like local and endtoend deadlines.},

In particular, it is difficult to assess the probability of rare events, though we are specifically interested in critical situations which will be infrequent for any reasonable system. For that purpose, we use a quantitative logic which enables us to specify criticality and other properties of simulation runs. An online evaluation of the logic permits us to define a procedure which guides the simulation towards critical situations and allows to estimate the risk of connected with the introduction of the assistance system.},

To save costs, the objective is to insert as many new tasks onto the system as possible. In this setting, to support early design decisions, we present an approximative and fast preanalysis of the system. We introduce sparetime analysis and the analysis of maximal allowed worstcase execution time to simplify the problem and to achieve a fast solving algorithm, which we implement as mixedinteger linear problem. We conduct experiments to investigate the scalability of the approach with the result that for input sizes of up to 160 tasks with up to 50% notyetdeployed tasks a solution is found in many cases within reasonable time, our machine needs in the average case 150s. With a reference example, taken from literature, we compare our approach with a similar method and show that our approach is faster.},

abstract = {Modelbased development aims at reducing the complexity of software development by the pervasive use of adequate models throughout the whole development process starting from early phases up to implementation. In this paper we present a conceptual framework to holistically classify developed models along different levels of abstraction. We do this by designing adequate abstractions for different development stages while ignoring the information that is not relevant at a particular development step or for a certain stakeholder. The abstraction is achieved in terms of the granularity level of the system under study (e. g. system, subsystem, subsubsystem) and in terms of the information that the models contain (e. g. specification of functionality, description of architecture, deployment on specific hardware). We also present the relation between models that describe different perspectives of the system or are at different granularity levels. However, we do not address the process to be followed for building these models.},

abstract = {We present "spotlight abstraction" as a generic abstraction technique for the analysis of systems comprising an unbounded number of communicating agents. The abstraction principle is heterogeneous in the sense that the behaviour of a finite number of agents is preserved while the others are only abstractly represented. The precision of the abstraction can be tuned by an iterative procedure based on the analysis of counterexamples. Going beyond existing work, we show how to use the spotlight principle for analysing systems where the physical position of agents is relevant. To this end, we put the spotlight on areas rather than on fixed sets of agents.},

abstract = {Software and system dependability is getting ever more important in embedded system design. Current industrial practice of modelbased analysis is supported by statetransition diagrammatic notations such as Statecharts. Stateoftheart modelling tools like STATEMATE support safety and failureeffect analysis at design time, but restricted to qualitative properties. This paper reports on a (plugin) extension of STATEMATE enabling the evaluation of quantitative dependability properties at design time. The extension is compositional in the way the model is augmented with probabilistic timing information. This fact is exploited in the construction of the underlying mathematical model, a uniform continuoustime Markov decision process, on which we are able to check requirements of the form: "The probability to hit a safetycritical system configuration within a mission time of 3 hours is at most 0.01." We give a detailed explanation of the construction and evaluation steps making this possible, and report on a nontrivial case study of a highspeed train signalling system where the tool has been applied successfully.},

Though both domains have their own characteristics we think that it is possible to apply the same core architec ture to support pilot as well driver centered design of assistance systems. This text shows how phenomena relevant in the automobile or aviation environment can be integrated in the same cognitive architecture.},

abstract = {We present a verification methodology for cooperating traffic agents covering analysis of cooperation strategies, realization of strategies through control, and implementation of control. For each layer, we provide dedicated approaches to formal verification of safety and stability properties of the design. The range of employed verification techniques invoked to span this verification space includes application of preverified design patterns, automatic synthesis of Lyapunov functions, constraint generation for parameterized designs, modelchecking in rich theories, and abstraction refinement. We illustrate this approach with a variant of the European Train Control System (ETCS), employing layer specific verification techniques to layer specific views of an ETCS design.},

abstract = {We present a novel approach to the automatic verification of LTL requirements of nonlinear discretetime hybrid systems. The verification tool uses an intervalbased constraint solver for nonlinear robust constraints to compute incrementally refined abstractions. Although the problem is undecidable, we prove termination of abstraction refinement based verification of such properties for the class of robust nonlinear hybrid systems, thus significantly extending previous semidecidability results. We argue, that safety critical control applications are robust hybrid systems. We give first results on the application of this approach to a variant of an aircraft collision avoidance protocol.},

We present a verification rule explicating the essence of employed design patters, guaranteeing global safety properties of the kind "a collision will never occur", and whose premises can either be established by offline analysis of the worstcase behavior of the involved traffic agents, or by purely local proofs, involving only a single traffic agent. In a companion paper we will show, how such local proof obligations can be discharged automatically. },

abstract = {We investigate the problem of generalizing acceleration techniques as found in recent satisfiability engines for conjunctive normal forms (CNFs) to linear constraint systems over the Booleans. The rationale behind this research is that rewriting the propositional formulae occurring in e.g. bounded model checking ({BMC}) [Biere, Cimatti,Zhu, 1999] to {CNF} requires a blowup in either the formula size (worstcase exponential) or in the number of propositional variables (linear, thus yielding a worstcase exponential blowup of the search space). We demonstrate that acceleration techniques like observation lists and lazy clause evaluation [Moskewicz e.a., 2001] as well as the more traditional nonchronological backtracking and learning techniques generalize smoothly to DavisPutnamlike resolution procedures for the very concise propositional logic of linear constraint systems over the Booleans. Despite the more expressive input language, the performance of our prototype implementation comes surprisingly close to that of stateoftheart {CNFSAT} engines like ZChaff [Moskewicz e.a., 2001]. First experiments with bounded modelconstruction problems show that the overhead in the satisfiability engine that can be attributed to the richer input language is often amortized by the conciseness gained in the propositional encoding of the {BMC} problem.},

Since standard Message Sequence Charts are neither expressive enough nor do they have a sufficient formal semantics we introduce Live Sequence Charts (LSCs) in order to overcome these deficiencies. Using a radiobased crossing control system as an example we outline how to embed LSCs into a modelbased development process. This entails a transition from scenariolike Sequence Charts used early in the design process to the graphical specification of system properties to be verified in later stages.},

abstract = {The European CENELEC norm now requires train system applications with critical safety integrity levels to be developed using formal methods, in particular supporting various forms of analysis to check for different correctness properties. In doing so, the CENELEC standard reflects the increasing need for advanced validation techniques in developing in particular also on board train system applications, which increasingly involve both complex and safety critical control units. This paper describes a methodology for developing train system applications based on powerful extensions of the Statemate modeling tool from ILogix Inc. The extension come in three dimensions:  Live Sequence Charts  a variant of the wellknown Message Sequence Charts of MSC2000 and the Sequence Diagrams in UML  are integrated with Statemate in order to allow capturing all interworkings between players such as onboard train control and train crossing control or between different trains, thus supporting the system development steps with a concise and semantically wellfounded representation of the critical communication protocols  Model Checking is integrated into Statemate to formally establish the correctness between such system requirements and a system specification developed in the industry standard CASE tool Statemate. This paper reports on an extension of the product version now marketed by ILogix, which supports formal verification of communication protocols captured as Live Sequence Charts. Model Checking can hence be used to verify all safety requirements on the system model, as well as to formally verify all system integration aspects using a virtual system integration as captured in Statemate.  Automatic Generation of Test Vectors from the Statemate specification model as well as from Scenarios can be used to validate the actual control units  in fact the test vectors can be downloaded to testrigs allowing hardwareintheloop tests of system components. The paper focuses on the overall methodology, which is explained using a trainsystem application, incorporating experiences from an ongoing cooperation with Bombardier transport systems.},

abstract = {Approaches to runtime checking have to track the execution of a software system and therefore have to deal with generating and processing execution events. Often these techniques are applied at the code level  either by inserting new source code prior to the compilation or by modifying the target code, e.g. Java byte code, before running the program. The jassda framework and tool enable runtime checking of Java programs against a CSPlike specification. For generating events it uses the Java Debug Interface (JDI) and thus no modifications to the code are necessary. Another advantage is that events are generated on demand, i.e. dynamically at runtime it is determined which events to generate for the current debug run without modifying the program itself. This paper shows how this event generation is done by the jassda framework.},

While this problem is known to be nonelementary when arbitrary length models are considered [Hansen1994], it turns out to be only NPcomplete when constrained to bounded length. As a corollary we obtain that model construction is in NP for the formulae actually encountered in case studies using Duration Calculus, as these have a certain smallmodel property. First experiments with a prototype implementation of the procedures demonstrate a competitive performance. \emph{Keywords:} Discretetime Duration Calculus; Model construction; Bounded model construction; Complexity},

The key element of this approach is the visual specification, as Live Sequence Charts (LSCs), of the properties to be checked. The LSCs are automatically translated into the input format for the SystemCbased checker engine, which indicates during simulation, if the property is fulfilled or produces a counterexample, if the property is violated. The entire process from the visual property specification to the checking is largely automated, which makes our approach accessible even for users which have not been trained in formal methods.} }

abstract = {While message sequence charts (MSCs) are widely used in industry to document the interworking of processes or objects, they are expressively quite weak, being based on the modest semantic notion of a partial ordering of events as defined, e.g., in the ITU standard. A highly expressive and rigorously defined MSC language is a must for serious, semantically meaningful tool support for usecases and scenarios. It is also a prerequisite to addressing what we regard as one of the central problems in behavioral specification of systems: relating scenariobased interobject specification to statemachine intraobject specification. This paper proposes an extension of MSCs, which we call live sequence charts (or LSCs), since our main extension deals with specifying "liveness", i.e., things that must occur. In fact, LSCs allow the distinction between possible and necessary behavior both globally, on the level of an entire chart and locally, when specifying events, conditions and progress over time within a chart. This makes it possible to specify forbidden scenarios, and enables naturally specified structuring constructs like as subcharts, branching and iteration.},

While computability issues concerning safety properties have been extensively studied, liveness properties have remained largely uninvestigated. In this article, we investigate decidability of state recurrence and of progress properties. First, we show that state recurrence and progress are in general undecidable for polynomial hybrid automata. Then, we demonstrate that they are closely related for hybrid automata subject to a simple model of noise, even though these automata are infinitestate systems. Based on this, we augment a semidecision procedure for recurrence with a semidecision method for lengthboundedness of paths in such a way that we obtain an automatic verification method for progress properties of linear and polynomial hybrid automata that may only fail on pathological, practically uninteresting cases. These cases are such that satisfaction of the desired progress property crucially depends on the complete absence of noise, a situation unlikely to occur in real hybrid systems.},

One such extension are Live Sequence Charts which allow to distinguish mandatory and possible behavior in protocol specifications. In the original language definition for LSCs the semantics are only described informally, although a sketch for a possible formalization has been provided as well. In this paper we intend to fill in the semantic blanks of the original LSC definition. Following the sketched path we define the semantics of an LSC by deriving a Timed Büchi Automata from it. We also consider qualitative and quantative timing aspects and subcharts.} }

abstract = {This paper presents the use of multithreaded processors in realtime architectures. In particular we will handle realtime applications with hard timing constraints. In our approach, events (e.g. timer interrupts, signals from the environment, etc) are distinguished into three classes according to the reaction times that have to be met. Since two of these classes are well known in realtime systems, we will focus on the new class, for which the special features of a multithreaded processor together with a realtime scheduler realized in hardware are employed. Doing so enables us to realize the handling of events from this new class in software while still meeting the demands on reaction time. Additionally, the predictability of the application and the ease of implementing them are increased. The processor, named MSPARC, which we developed to support these features, is based on block multithreading and is outlined in this paper, too. We then present an architecture, designed for rapid prototyping of embedded systems, to show the feasibility of this approach. Finally, a case study shows the potential of multithreading for embedded systems.},

The first one was focused on setting the end users requirements for UML modeling of realtime embedded systems. The second has been focused on design and implementation techniques proposals and experiences. The third has been centered on formal techniques for the validation of the applications from their UML model. } }

This reduces the chances of incorrect system specifications and can sometimes reduce also the actual model checking time. The drawback of this technique lies in its heterogeneity. In fact, usually monitors are defined at the implementation level of the device model under test. In this paper we present a more general approach based on the idea of abstracting monitors definition from the model level up to the specification level without imposing further constraints on the current model checking techniques. A test case from the telecom domain is used to illustrate the definition and use of this type of embedded monitors, showing advantages and benefits related to their application. },

abstract = {This work presents a firstorder model checking procedure that verifies systems with potentially infinite data spaces with respect to firstorder CTL specification. The procedure relies on a partition of the system variables into \emph{control} and \emph{data}. While control values are expanded into BDDrepresentations, data values enter in form of their properties relevant to the verification task. The algorithm is completely automatic. If the algorithm terminates, it has generated a firstorder verification condition on the data space which characterizes the system's correctness. Termination can be guaranteed for a class that properly includes the data independent systems, defined in \cite{Wol86}. The procedure works like a symbolic model checker on the control part. The data part is handled by annotating each controlexpanded state of the system by a firstorder formula. These formulas characterize, for each state, the set of data valuations that altogether make the specification true for the system. A novel part of our work is that the firstorder annotations are represented as BDDs and are manipulated symbolically. Since the formulas are represented by BDDs, we get ''for free'' propositional simplifications. Moreover, the canonical representation provided by BDDs makes it easier to detect termination of our model checking procedure. Finally, the encoding of predicates as boolean variables enables \emph{sharing} of subformulas among the formulas produced by the model checking procedure. This work improves \cite{DHGcharme95},
where we extended \emph{explicit} model checking algorithms. In contrast, this paper shows how to cast firstorder model checking into BDDbased representations. Thus, for complex control aspects of the design the full power of symbolic model checking is provided, while at the same time temporal reasoning is supported by the generation of a verification condition in cases where the data complexity is too high for ordinary procedures.},

We demonstrate our verification environment on a sample avionics case study which is provided by our project partner ESG. This case study is about a faulttolerant Helicopter Monitoring System of a Helicopter with two engines. There are two independent tasks which are scheduled periodically by a control task. For each engine the first task compares a computed and a measured rotations per minute (rpm) value. If the difference raises above a given threshold, the task generates an alarm displayed to the pilot. Then the pilot has to decide whether to switch off the engine or not. The second task monitors the remaining fuel of the aircraft. It first computes two values to determine the remaining amount of fuel. One value is computed by fuel throughput and one is computed by the initial amount of fuel and the flight distance. Again an alarm is generated if the two values differ too much. Otherwise the weighted average of these values is assumed to be the remaining amount of fuel. An alarm is also generated if this value reaches a critical threshold. All generated alarms have to be acknowledged by the pilot. The control task schedules the above two tasks and also accepts commands given by the pilot by performing the corresponding actions. We present some results we got on verifying some relevant properties of the faulttolerant monitoring system with our toolset. },

A highly expressive and rigorously defined MSC language is a must for serious, semantically meaningful tool support for usecases and scenarios. It is also a prerequisite to addressing what we regard as one of the central problems in behavioral specification of systems: relating scenariobased interobject specification to statemachine intraobject specification. This paper proposes an extension of MSCs, which we call live sequence charts (or LSCs), since our main extension deals with specifying "liveness", i.e., things that must occur. In fact, LSCs allow the distinction between possible and necessary behavior both globally, on the level of an entire chart and locally, when specifying events, conditions and progress over time within a chart. This also makes it possible to specify forbidden scenarios, and strengthens structuring constructs like as subcharts, branching and iteration.},

abstract = {This paper presents a reference semantics for a verification tool currently under development allowing to verify temporal properties of embedded control systems modelled using the STATEMATE system. The semantics reported differs from others reported in the literature by faithfully modelling the semantics as supported in the STATEMATE simulation tool. It differs from the recent paper by Harel and Naamad by providing a {\em compositional\/} semantics, a prerequisite for the support of {\em compositional verification methods},
and by the degree of mathematical rigour. We use a variant of \textit{synchronous transition systems} introduced by Manna and Pnueli as base model for our semantics. \par The STATEMATE modelling language constructs covered in this paper are \textit{Activity charts},
modelling the functional decomposition of a design into subunits called \textit{activities} as well as the \textit{information flow} between these, and \textit{Statecharts},
modelling reactive behaviour using the well established approach of hierarchically organized statemachines. We strive for a verification approach which is compositional w.r.t.\ the decomposition of systems into subsystems. This will allow activities of ``reasonable'' complexity to be verified using \textit{symbolic model checking}. \par Larger activities will be verified on the basis of proofsystems relating properties of individual activities to properties of compound activities, using the well known \textit{assumption commitment paradigm}. A key topic for this paper is the construction of so called \textit{compositional models},
which are ``rich enough'' to model the STATEMATE parallel composition by intersection of the infinite traces generated by the components of the parallel composition. Roughly, compositional models have to provide room for padding arbitrary (but still ``legal'') environment interactions into computations of a component. Alternatively, the construction of compositional models can be phrased as a requirement on the model to support a sufficiently rich class of \textit{observables} for assumptioncommitment style reasoning to be complete. In this sense, this paper derives the set of atomic propositions included as observables in the assumptioncommitment style temporal logic supported by the verification tool. \par The richness of the STATEMATE modelling languages forbids a complete treatment within such a formal semantics. While Harel and Naamad elaborate in a detailed fashion the construction of compound transitions from transition segments, we take this as given in this paper. We also abstract from the concrete syntax of action annotations, but keep them rich enough to show how all the associated intricacies can be handled formally.} }

Our approach is in orthogonal to most of the existing ORparallel models such as SRI, Aurora and Andorra models which aim to raise efficiency of ORparallel execution by incorporating different strategies for process control and environment management. The preliminary simulation results of the model enhanced with sharing have shown a significant reduction of computation tree and heap space used for the evaluation of nondeterministic programs. More importantly, comparied with nonshared ORparallel models, our model enhanced with sharing promises a speed up for nondeterministic programs.} }

They have proven to be very valuable for easy to understand specifications of critical system requirements. Over the past few years, quantitative (real time) timing aspects have gained increasing attendance in formal specification and verification. Intuitively, adding real time requirements to the graphical denotation of symbolic timing diagrams is easily accomplished by annotating constraint arcs to carry time intervals. In this paper we define the formal semantics of real time timing diagrams by a translation to timed propositional temporal logic. It is intended as technical reference and assumes some knowledge on STD.

In the case of socalled linear hybrid automata this formalization supports semidecision procedures for state reachability, yet no decision procedures due to inherent undecidability. Thus, unlike finite or timed automata, already linear hybrid automata are outofscope of fully automatic verification. In this article, we devise a new semidecision method for safety of linear and polynomial hybrid systems which may only fail on pathological, practically uninteresting cases. These remaining cases are such that their safety depends on the {\em complete} absence of noise, a situation unlikely to occur in real hybrid systems. Furthermore, we show that if low probability effects of noise are ignored akin to the way they are suppressed in digital modelling then safety becomes fully decidable.},

While this was formerly taken as an indication that keypress verification with respect to elaborate DC specifications were impossible, we show that modelchecking {\em realistic} designs is nevertheless feasible. The key issue is that the classical undecidability results rely on a notion of validity of a formula that refers to a class of models which is considerably richer than the possible behaviours of embedded realtime systems. By analyzing two suitably sparser model classes we obtain modelchecking procedures for rich subsets of Duration Calculus. Together with undecidability results also obtained, this sheds light upon the exact borderline between decidability and undecidability of Duration Calculi and related logics.},

abstract = {Since Muller and Schupp have shown in 1985 that monadic secondorder logic (MSOL) is decidable for contextfree graphs, several specialized procedures have been developed for related problems, mostly for sublogics like the modal mucalculus, or even its alternationfree fragment. This work shows the decidability of S1S, the trace version of MSOL, for the richer set of \emph{macro graphs}. The generation mechanism of macro graphs is of higherorder nature and relates to the contextfree one like macro grammars [Fischer, 1968] relate to contextfree grammars. Technically, the result follows from the decidability of the emptiness problem of the trace language of a macro graph with fairness. The decision procedure is given in form of a tableau system. Soundness and completeness follow from the relation of the (finite) tableaux to their infinite unfoldings. This kind of proof promises to be helpful in the derivation of further results.},

In [Brown, Clarke, Grumberg 1988] an analogue definition is given for state based systems (Kripke structures) and it is shown that the notion of bisimulation coincides with the equivalence induced by the temporal logic CTL*. We will generalize their results concerning weak bisimulation to reactive systems. A reactive system is an open system interacting with its environment, and consequently its behaviour depends on the actions of the environment. Hence an equivalence relation for reactive systems should include the reactions of the environment. This leads to a notion of relativized bisimulation. For action based systems such a context dependent bisimulation is given in [Larsen 1987], where the environment constraints are given by an action system too. We define a relativized (weak) bisimulation for Kripke structures where the environment constraints are given by a temporal logic specification. We show that this notion of relativized bisimulation coincides with the relativized equivalence induced by the temporal logic CTL* without the nexttimeoperator. Furthermore, we show that it is possible to construct a CTL formula which uniquely characterizes a Kripke structure relatively to a given environment. } }

abstract = {Our aim is a modular verification method for concurrent systems. To verify a module separated from the other components we have to assume some (correct) behaviour of these components concerning the interactions with the module under consideration. These reactions of the other modules can be described by liveness properties. Hence in a modular verification method we have to prove a formula under some liveness assumptions. A logic which is able to express the correctness of a subsystem under some liveness assumption is e.g.\ CTL* or only its linear time part TL. But model checking for CTL* is exponential in the size of a given formula. Hence, often CTL is used instead of CTL* in specifications of concurrent systems as this logic has a linear model checking algorithm. But CTL has a restricted expressive power, e.g.\ it is not expressible that some property holds under some liveness assumptions. In this paper we define a logic LCTL, which is an extension of CTL where quantifications over paths are interpreted with respect to some liveness assumptions.I.e., formulae of LCTL are pairs $(l,f)$ where $l$ is a liveness assumption (expressed in TL) and $f$ is a CTL formula. } }

abstract = {In this thesis we develop a theory for compositional verification of reactive systems in the framework of assumption/commitment style logic. Due to the fact that the state space of a system may grow exponentially with the number of its components (a phenomenon commonly referred to as the state explosion problem) modular and compositional verification methods are necessary to verify the correctness of large programs and systems. \parThe background of our work is twofold: On one hand it is based on temporal logic which is a comprehensive and well established specification language for expressing a wide spectrum of properties of reactive systems. On the other hand {\em assumption/commitment} style specifications have to be used to express the dependency of the behaviour of a system on the interaction with its environment; so the specification of a system is given always relatively to an expected behaviour of its environment. \par In this thesis we combine the theory of assumption/commitment specifications with the theory of {\em branching time} temporal logic and present the logic MCTL* as an extension of the branching time temporal logic CTL*. We develop a design methodology for compositional verification using assumption/commitment specifications of branching time temporal logic which subsumes the linear time approach. \par Our compositional approach overcomes the state explosion problem in a way that basic components of a complex system can be verified automatically using a special model checking algorithm. We present an efficient model checking algorithm for assumption/commitment specifications which is an extension of the wellknown CTL model checker. To verify complex systems proof rules are given to derive properties of the global systems from already established properties of its components. The presented proof calculus is complete for finite systems. The feasibility of our approach is demonstrated by typical examples. \par Theoretical explorations of the temporal logic MCTL* are given. We classify the logic MCTL* within the hierarchy of branching time temporal logics and show that MCTL* subsumes the logic CTL* and can be embedded into the $\mu$calculus of alternation depth 2. This embedding is achieved by means of a translation into ECTL, an automata extension of CTL*. Furthermore, a uniform semantics definition for CTL*, fair CTL*, MCTL* and others is given introducing the notion of extended computation trees. } }

abstract = {Data used by parallel programs can be divided into classes, based on how threads access it. For different classes of data different coherence mechanisms might be optimal. This paper presents four primitives designed for use in a shared memory multiprocessor system, where each processor has its private cache. Using these primitives, programmers can implement those coherence models that are best suited to their applications. The paper gives a description of the primitives and some implementation details. },

abstract = { Most strong cache coherence protocols provide a sequential consistent memory model. Weak coherence models often give an, albeit restricted, view of this model, too. However, there are many different possibilities to write parallel programs and not all of them are based on sequential consistency. This paper presents a new cache coherence protocol that provides many different ways of implementing coherence and synchronization. Using this protocol threads can exploit knowledge about how they use data and decide which coherence scheme to use. An implementation of the protocol in a NUMA environment is described in detail and discussed. This is a long version of "A RISC Approach to Weak Cache Coherence" by the same authors.},

abstract = { During the last few years many different memory consistency protocols have been proposed. These range from strong models like sequential consistency or processor consistency to weak ones like weak ordering, release consistency and SCNF. Implementations of these protocols are usually transparent to application programs: They try to hide as much detail as possible, usually leaving 'well behaved' applications with a sequential consistent memory view. There are two reasons why a different approach to memory consistency is chosen in this paper. On one hand this transparency of protocols imposes a limit on the amount of information about data access categories that can be given by applications. More information could reduce coherence overhead substantially. On the other hand sequential consistency is not the only feasible programming model for writing parallel programs. Most applications do not rely on the strong limitations given by it, because they synchronize to access shared data. We therefore propose processor primitives that allow applications to implement different consistency schemes for accesses to different data objects. We also describe the implementation of these primitives in a busbased shared memory NUMAArchitecture. To show the feasibility of such an architecture, preliminary performance results using orparallel Prolog programs are given.},

The heart of the prover is built by two powerful industrial verification tools: A (compositional) symbolic model checker (developed by SIEMENS), and the LAMBDAtheorem prover (developed by AHL). The aim of this paper is to describe (1) the various tools integrated in the prover, (2) the graphical specification language STD with its associated design methodology, and (3) to explain how proofs about {\em generic} (parameterized) designs are performed in the prover, using a combination of automatic and interactive reasoning.},

The visual formalism {\em STD} ({\em S}ymbolic {\em T}iming {\em D}iagrams) was developed continuously since 1993 by OFFIS as a specification method, which satisfies several needs: (1) It is based on the principles used in the familiar notation of timing diagrams (as conventionally used by hardware designers). (2) It is a method amenable to formal verification, using stateofthe art verification tools efficiently (in particular, symbolic modelchecking). (3) It supports {\em compositional} verification, which is an approach to verify large designs in a compositional way (breaking up proofs of requirements stated for a full design into a sequence of smaller proof tasks, which imply the global proof task). The formalism (with the supporting tools) has been integrated into an established verification environment ({\em CheckOffM}), which allows to verify industrialscale designs by modelchecking.},
