Cuong Chau ACL2 Seminar March 10, 2017 Modeling and Verifying Self-Timed Circuits Using an Asynchronous Extension of the DE System Abstract: In this talk, I will present in more detail our framework for asynchronous circuit modeling and verification. I demonstrate our framework by modeling and verifying the functional correctness of a 32-bit self-timed serial adder. I will also show my attempt to state theorems for all modules in a way that enables compositional (hierarchical) reasoning in our framework.
