Verifying whether a building block conforms to a specific interface protocol is one of the important steps in a platform-based system-on-a-chip design methodology. There are limitations for most of the existing methods for interface protocol compliance verification. Simulation-based methods have the false positive problem while formal property checking methods may suffer from memory explosion and excessive runtime. In this paper, we propose a novel approach for interface protocol compliance verification. The properties of the interface protocol are first specified as a specification FSM. Then the compliance of interface logic is formally verified at the higher FSM level so that the required memory and runtime can be greatly reduced. Finally, it is shown theoretically and experimentally that the proposed algorithm possesses acceptably low time complexity for practical applications.
