Explicit model checking
In computer science, model checking or property checking is a method for checking whether a finite-state model of a system meets a given specification (also known as correctness). This is typically associated with hardware or software systems, where the specification contains liveness requirements (such as … See more Property checking is used for verification when two descriptions are not equivalent. During refinement, the specification is complemented with details that are unnecessary in the higher-level specification. There … See more Instead of enumerating reachable states one at a time, the state space can sometimes be traversed more efficiently by considering … See more Model checking is also studied in the field of computational complexity theory.

WebThere exist several approaches for veri cation, ranging from explicit model check-ing [4] via BDD based model checking [3] to SAT based model checking [23]. For Petri nets, the variety of methods is larger than elsewhere since we can also use unfoldings [6] and the whole bandwidth of Petri net structure theory. The veri cation methods have in ...

Compute the Buchi automaton A corresponding to the system M 2. Compute the synchronous product P of A and B’ • Product computation defines “accepting” states of P based on those of B’ 3.
