Verification Artifacts in Cooperative Verification: Survey and Unifying Component Framework
This work addresses the challenge of interoperability in software verification for researchers and practitioners, but it is incremental as it builds on existing survey and formalization efforts.
The paper tackles the problem of combining verification approaches to improve software verification by surveying cooperative verification methods and formalizing verification artifacts in a unified framework to fix their semantics.
The goal of cooperative verification is to combine verification approaches in such a way that they work together to verify a system model. In particular, cooperative verifiers provide exchangeable information (verification artifacts) to other verifiers or consume such information from other verifiers with the goal of increasing the overall effectiveness and efficiency of the verification process. This paper first gives an overview over approaches for leveraging strengths of different techniques, algorithms, and tools in order to increase the power and abilities of the state of the art in software verification. Second, we specifically outline cooperative verification approaches and discuss their employed verification artifacts. We formalize all artifacts in a uniform way, thereby fixing their semantics and providing verifiers with a precise meaning of the exchanged information.
