The NUXMV Symbolic Model Checker

This paper describes the NuXmv symbolic model checker for finite-and infinite-state synchronous transition systems. NuXmv is the evolution of the NuSMV open source model checker. It builds on and extends NuSMV along two main directions. For finite-state systems it complements the basic verification techniques of NuSMV with state-of-the-art verification algorithms. For infinitestate systems, it extends the NuSMV language with new data types, namely Integers and Reals, and it provides advanced S MT-based model checking techniques. Besides extended functionalities, NuXmv has been optimized in terms of performance to be competitive with the state of the art. NuXmv has been used in several industrial projects as verification back-end, and it is the basis for several extensions to cope with requirements analysis, contract based design, model checking of hybrid systems, safety assessment, and software model checking.
