Bit-precise software verification is an important and difficult problem. While there has been an amazing progress in SAT solving, Satisfiability Modulo Theory of Bit Vectors, and bit-precise Bounded Model Checking, proving bit-precise safety, i.e. synthesizing a safe inductive invariant, remains a challenge. In this paper, we present FrankenBit — a tool that combines bit-precise invariant synthesis with BMC counterexample search. As the name suggests, FrankenBit combines a large variety of existing verification tools and techniques, including LLBMC, UFO, Z3, Boolector, MiniSAT and STP.
