Abstract

This paper describes Split, a compositional verifier for safety and general Ltl properties of shared-variable, multi-threaded programs The foundation is a computation of compact local invariants, one for each process, which are used for constructing a proof for the property An automatic refinement procedure gradually exposes more local information, until a decisive result (proof/disproof) is obtained.
