CoveRT: A Coverage Reporting Tool for Analog Mixed-Signal Designs

Coverage monitoring has become increasingly significant for analog designs considering the life cycle of analog design IPs that are first designed and verified in isolation and then used in a wide variety of contexts in one or more integrated circuits. The behavioral artifacts relevant for coverage in the analog and mixed signal (AMS) domain are very different from the digital domain, and is the primary motivation behind the proposed tool, CoveRT. This paper introduces the AMS coverage primitives, the challenges in monitoring the coverage by handshaking with the simulation platform, and the salient features of our methodology. To the best of our knowledge, CoveRT is the first AMS coverage monitoring tool of its kind which works with commercial simulators.
