Abstract

Symbolic model checking is a very successful formal verification technique, classically based on Binary Decision Diagrams (BDDs). Recently, propositional satisfiability (SAT) techniques have been proposed as a computational basis for symbolic model checking, and proved to be an effective alternative to BDD-based techniques. In this paper we show how BDD-based and SAT-based techniques have been effectively integrated within the NuSMV symbolic model checker.
