description to be presented at CAV 2004 . SAL 2 ?

SAL 2 augments the specification language and explicit-state model checker of SAL 1 with high-performance symbolic and bounded model checkers, and with novel infinite bounded and witnessmodel checkers. The bounded model checker can use several different SAT solvers, while the infinite bounded model checker similarly can use several different ground decision procedures. SAL 2 provides a scriptable API for its basic model checking and analysis functions that can be used to extend the system. All four new model checkers are implemented using this interface. Its high-level specification language and wide range of model checkers make SAL convenient for those seeking a ready-to-use solution, while its scriptability and flexible choice of backend analyzers should make it attractive to those seeking an experimental platform.
