The VMT-LIB Language and Tools

We present VMT-LIB, a language for the representation of verification problems of linear-time temporal properties on infinite-state symbolic transition systems. VMT-LIB is an extension of the standard SMT-LIB language for SMT solvers, developed with the goal of facilitating the interoperability and exchange of benchmark problems among different verification tools. Besides describing its syntax and semantics, we also present a set of open-source tools to work with the language.
