Abstractcvc5 is the latest SMT solver in the cooperating validity checker series and builds on the successful code base of CVC4. This paper serves as a comprehensive system description of cvc5 ’s architectural design and highlights the major features and components introduced since CVC4  1.8. We evaluate cvc5 ’s performance on all benchmarks in SMT-LIB and provide a comparison against CVC4 and Z3.

In this paper, we discuss the most important changes and new features introduced with version 2.0 of our SMT solver Boolector, which placed first in the QF BV and QF ABV tracks of the SMT competition 2014. We further outline some features and techniques that were not yet described in the context of Boolector.
