A Counterexample-Guided Refinement Tool for Open Procedural Programs

Abstract: We present a model checking tool based on game semantics and CSP for verifying safety properties of software, such as assertion violations or array-out-of-bounds errors. The tool implements a data-abstraction refinement procedure applicable to open programs with infinite integer types. The procedure is guaranteed to terminate for unsafe inputs.
