VeriCoq: A Verilog-to-Coq converter for proof-carrying hardware automation
Mohammad-Mahdi Bidmeshki, Yiorgos Makris · 2015
Proof carrying hardware intellectual property (PCHIP) introduces a new framework in which a hardware (semiconductor) Intellectual Property (IP) is accompanied by formal proofs of certain security-related properties, ensuring that the acquired IP is trustworthy and free from hardware Trojans. In the PCHIP framework, conversion of the design from a hardware description language (HDL) to a formal representation is an essential step. Towards automating this process, herein we introduce VeriCoq, a converter of designs described in Register Transfer Level (RTL) Verilog to their corresponding representation in the Coq theorem proving language, based on the rules defined in the PCHIP framework. VeriCoq supports most of the synthesizable Verilog constructs and is the first step towards automating the entire framework, in order to simplify adoption of PCHIP by hardware IP developers and consumers and, thereby, increase IP trustworthiness.
