Abstract: We propose a two-stage exact approach for identifying finite-state models of function blocks based on given execution traces. First, a base finite-state model is inferred with a method based on translation to the Boolean satisfiability problem, and then, the base model is generalized by inferring minimal guard conditions of the state machine with a method based on translation to the constraint satisfaction problem.
