    Component-based CEGAR - Building Software Verifiers from Off-the-Shelf Components
    (Software Engineering 2023, 2023) Beyer, Dirk; Haltermann, Jan; Lemberger, Thomas; Wehrheim, Heike
    Software verification tools typically consist of tighly coupled components, thereby precluding the easy integration of off-the-shelf components. We propose to decompose software verification into independent subtasks, each task being implemented by an own component communicating with other components via clearly defined interfaces. We apply this idea of decomposition to one of the most frequently used techniques in software verification: CEGAR. Our decomposition, called component-based CEGAR (C-CEGAR), comprises three components: An abstract model explorer, a feasibility checker and a precision refiner. It allows employing conceptually different components for each task within one instance. Our evaluation shows that C-CEGAR has, compared to a monolithic CEGAR-implementation, a similar efficiency and that the precision in solving verification tasks even increases.
