This paper describes version 2 of the NuSMV tool. NuSMV is a symbolic model\ud
checker originated from the reengineering, reimplementation and extension of\ud
SMV, the original BDD-based model checker developed at CMU. The Nu-\ud
SMV project aims at the development of a state-of-the-art symbolic model\ud
checker, designed to be applicable in technology transfer projects: it is a well\ud
structured, open, flexible and documented platform for model checking, and is\ud
robust and close to industrial systems standards
