Evolving the Coverage-Driven Verification Flow

Over the past decade, coverage-driven verification has emerged as a means to deal with increasing design complexity and ever more constrained schedules. Among the benefits of the new methodology—a dramatically expanded set of verification metrics and tools providing much improved visibility into the verification process. However, coverage-driven verification flows are still beset by challenges, including how to efficiently achieve coverage closure. Matthew Ballance describes how inFact's coverage-driven stimulus generator is helping to respond to these challenges with unique algorithms that help to simultaneously target multiple independent coverage goals.
