Abstract: The reliability of circuitry implemented on FPGAs (Field Programmable Gate Arrays) affects the critical mission life directly. FPGAs design should be thoroughly verified in order to meet the requirement of high reliability. This paper analyzed traditional function verification and described the development of verification techniques and methodologies. We proposed and implemented a layered general purpose verification platform which is utilized to verify two DUT. The verification results exhibit that our platform is suitable for diverse applications and enhances the coverage and efficiency.
