| dc.description.abstract | Petri nets are a widely used formalism to describe and analyze critical systems. It is in particular well suited for systems with concurrency like cache coherence protocols, fault-tolerant distributed systems or security critical protocols. The verification approaches for Petri nets are most often based on enumerative approaches which allow for analyzing complex, often temporal, properties. Dataflow languages are widely used in safety critical systems. There are several state-of-the-art model-checkers for these languages. While the properties that can be verified are generally limited to invariants, it is possible to encode some interesting properties of Petri nets as invariants which makes them accessible for powerful analysis methods based on modern SMT and SAT solvers. The SpiNat approach transforms Petri net into synchronous dataflow language models. This allows for using predicate abstraction and the theory of unbounded integers allows to analyze the potentially unbounded markings of Petri nets using model-checking tools for languages like Lustre. The presented approach is orthogonal to enumeration based approaches for Petri net analysis and allows benefiting from any increase in efficiency of industrial strength SMT-based model-checkers like kind2 and Jkind | en |
