ReWire is a programming language designed to support a purely functional style of hardware design. Previous research has demonstrated the efficacy of ReWire as a hardware design language, and that ReWire provides a powerful framework for verification via simple ""Bird-Wadler"" style equational reasoning. In this talk, I will discuss ongoing effors to mechanize the metatheory of ReWire in Coq, including proofs of type safety, strong normalization, and the soundness of ReWire's equational theory.
