Bounded Invariant Checking for Stateflow Programs [article]

Predrag Filipovikj and Dilian Gurov and Mattias Nyberg
2021 arXiv   pre-print
Next, we define bounded invariant checking for STS over symbolic configurations as a satisfiability problem.  ...  To address these challenges, we lay here the foundations of a scalable technique for provably correct formal analysis of Stateflow models, with respect to invariant properties, based on bounded model checking  ...  The authors would also like to thank Gustav Ung for his valuable comments and constructive feedback.  ...

Invisible formal methods for embedded control systems

A. Tiwari, N. Shankar, J. Rushby
2003 Proceedings of the IEEE  
As an instance of invisible formal methods, we describe techniques to check inductive invariants, or extended types, for hybrid systems and compute discrete finite state abstractions automatically to perform  ...  We also briefly discuss the problem of translating models in Simulink/Stateflow language, which is widely used in practice, into the modeling formalisms, like hybrid automata, for which analysis tools  ...  Analysis tools for Simulink/Stateflow or hybrid models include symbolic simulation, invariance checking, typechecking, abstraction, and model checking.  ...

Program Semantics in Model-Based WCET Analysis: A State of the Art Perspective

Mihail Asavoae, Claire Maiza, Pascal Raymond, Marc Herbstritt
2013 Worst-Case Execution Time Analysis  
When the application is a hard real-time program, such guarantees could be deadlines, thus making the computation of worst-case execution time (WCET) bounds mandatory.  ...  This paper overviews, in the context of WCET analysis, what are the existing techniques to extract, express and exploit the program semantics along the model-based development workflow.  ...  A model-based approach uses representations for the program states and the path exploration is performed with model checking techniques.  ...
