    Abstract
    Techniques for software verification are typically realized as cohesive units of software with tightly coupled components. This makes it difficult to re-use components, and the potential for workload distribution is limited. Innovations in software verification might find their way into practice faster if provided in smaller, more specialized components. In this paper, we propose to strictly decompose software verification: the verification task is split into independent subtasks, implemented by only loosely coupled components communicating via clearly defined interfaces. We apply this decomposition concept to one of the most frequently employed techniques in software verification: counterexample-guided abstraction refinement (CEGAR). CEGAR is a technique to iteratively compute an abstract model of the system. We develop a decomposition of CEGAR into independent components with clearly defined interfaces that are based on existing, standardized exchange formats. Its realization component-based CEGAR (C-CEGAR) concerns the three core tasks of CEGAR: abstract-model exploration, feasibility check, and precision refinement. We experimentally show that - despite the necessity of exchanging complex data via interfaces - the efficiency thereby only reduces by a small constant factor while the precision in solving verification tasks even increases. We furthermore illustrate the advantages of C-CEGAR by experimenting with different implementations of components, thereby further increasing the overall effectiveness and testing that substitution of components works well.

    We present Infer-SV, a wrapper that adapts Infer for SV-COMP. Infer is a static-analysis tool for C and other languages, developed by Facebook and used by multiple large companies. It is strongly aimed at industry and the internal use at Facebook. Despite its popularity, there are no reported numbers on its precision and efficiency. With Infer-SV, we take a first step towards an objective comparison of Infer with other SV-COMP participants from academia and industry.

    Abstract
    Interpolation-based model checking (McMillan, 2003) is a formal-verification algorithm, which was originally devised to verify safety properties of finite-state transition systems. The algorithm is state-of-the-art in hardware model checking. It derives interpolants from unsatisfiable BMC queries, and collects them to construct an overapproximation of the set of reachable states. Unlike other formal-verification algorithms, such as k-induction or PDR, which have been extended to handle infinite-state systems and investigated for program analysis, McMillan's interpolation-based model checking algorithm from 2003 has not been used to verify programs so far. This paper closes this significant, 19 years old gap in knowledge by adopting the algorithm to software verification. We implemented it in the verification framework CPAchecker, and evaluated the implementation against other state-of-the-art software-verification techniques over the largest publicly available benchmark suite of C safety-verification tasks. The evaluation demonstrates that interpolation-based model checking is competitive among other algorithms in terms of both the number of solved verification tasks and the run-time efficiency. Our results might have important implications for software verification, because researchers and developers now have a richer set of approaches to choose from.
