Assessing the safety and the dependability of a system is one of the systems engineer’s main targets. Formal tools, however powerful they may be to meet these issues, are often too cumbersome and complex to use. In this paper, we show that efficient formal methods can be used on high-level models used in Systems Engineering to achieve some verification and validation processes. We give an overview of ongoing work on the translation of EFFBD-like models to time Petri nets, using model transformation and meta-modeling. We also present some encouraging results obtained with a prototype translation tool.
