Our verified bit blasting algorithm supports the full QF_BV logic of SMT-LIB; it is specified and formally verified in the proof assistant Coq .  ...  AbstractWe present a certified SMT QF_BV solver CoqQFBV built from a verified bit blasting algorithm, Kissat, and the verified SAT certificate checker GratChk in this paper.  ...  Our construction is based on a new formal bit-vector theory coq-nbits (Sect. 4). In coq-nbits, we define bit-vectors and their functions on top of the Coq data type for Boolean sequences.  ...
