PVS is a mechanized environment for formal specification and verification. PVS consists of a specification language, a large number of predefined theories, a type checker, an interactive theorem prover that supports the use of several decision procedures and a symbolic model checker, various utilities including a code generator and a random tester, documentation, formalized libraries, and examples that illustrate different methods of using the system in several application areas.
