Bitwuzla

Abstract Bitwuzla is a new SMT solver for the quantifier-free and quantified theories of fixed-size bit-vectors, arrays, floating-point arithmetic, and uninterpreted functions. This paper serves as a comprehensive system description of its architecture and components. We evaluate Bitwuzla’s performance on all benchmarks of supported logics in SMT-LIB and provide a comparison against other state-of-the-art SMT solvers.
