Model Execution and Debugging: A process to leverage existing tools

International audienceModel checking is an effective technique for the verification of critical systems. However, it relies on behavioral models which writing and verification is most of time costly. Thus, those models shall be validated and debugged thoroughly, and simulation, i.e. model execution, can be used for that purpose. To reduce the development costs of simulators and ensure their behavioral consistency with model verifiers, we advocate the reuse of parts of the model verification toolchain to implement them. To support this claim, this paper proposes a method illustrated with a realistic case study applied to FIACRE behavioral models. The approach relies on the creation and exploitation of relations between models representing the information required by the user on the one hand, and information produced by the tools, on the other hand
