| Summary: | Verification is critical to the design of large and complex systems. SPIN is a well-known and extensively used verification tool. In this paper, we consider two tool chains, one existing, WSAT, and one introduced here, that support using SPIN to model check systems specified as Simulink Stateflow models. We present algorithms for doing the necessary translations and present empirical results that show the chain using tools introduced in this paper performs better than the one using the existing WSAT tool. We also show that these tools allow SPIN to be used for model checking nondeterministic Stateflow models in addition to deterministic ones.
