The paper presents a novel approach to formal verification and debugging of modular (2n − 1) multipliers. It takes advantage of the regular array structure of such multipliers and models them as a system of linear equations.

摘要

The paper presents a novel approach to formal verification and debugging of modular (2n − 1) multipliers. It takes advantage of the regular array structure of such multipliers and models them as a system of linear equations. The method is significantly more effective than the popular symbolic computer algebra and algebraic rewriting techniques, allowing verification of 512-bit multipliers in single minutes. Furthermore, it naturally enables debugging as an integral part of the verification process, an important feature not offered by other known approaches.
