This paper presents a model checking tool, SatAbs, that implements a predicate abstraction
refinement loop. Existing software verification tools such as Slam, Blast, or Magic use …

Predicate abstraction is a major method for verification of software. However, the generation
of the abstract Boolean program from the set of predicates and the original program suffers …

We present a framework for model checking concurrent software systems which incorporates
both states and events. Contrary to other state/event approaches, our work also integrates …

This paper describes OpenSMT, an incremental, efficient, and open-source SMT-solver.
OpenSMT has been specifically designed to be easily extended with new theory-solvers, in …

Variants of general-purpose programming languages, like SystemC, are increasingly used
to specify system designs that have both hardware and software parts. The system-level …

Modern termination provers rely on a safety checker to construct disjunctively well-founded
transition invariants. This safety check is known to be the bottleneck of the procedure. We …

Formally verifying smart contracts is important due to their immutable nature, usual open source
licenses, and high financial incentives for exploits. Since 2019 the Ethereum Foundation’…

The Ethereum platform is a public, distributed, blockchain-based database that is maintained
by independent parties. A user interacts with Ethereum by writing programs and having …

This paper describes a major revision of the OpenSMT solver developed since 2008. The
version 2 significantly improves its predecessor by providing a design that supports extensions…

During model checking of software against various specifications, it is often the case that the
same parts of the program have to be modeled/verified multiple times. To reduce the overall …
