Today, most design managers depend on some sort of verification-coverage metrics to answer three primary questions, according to Mentor Graphics' chief verification scientist, Harry Foster: Where have I been, where am I going, and when will I get there? But there are many coverage metrics, coming from various tools and meaning different things. It is vital for design managers to understand what each sort of metric really means. Equally important, the manager must be able to blend a variety of metrics into one picture that will answer Foster's three questions. Most important, the manager must answer correctly another version of the third question: Whenrnis it time to stop? The decision not only requires a fusion of diverse metrics, but also depends upon a detailed verification plan that has existed since the early days of the architectural design and hasrnsince grown and blossomed right along with the design.
