The few of you who regularly read this blog, may have wondered what happened to my friend Coverage in the past 3 months. It turns out he has been on a worldwide quest to collect wisdom from verification experts near and far. The other day I bumped into him and he was clearly troubled. After some prodding he grudgingly admitted to his concerns. “People are amassing coverage data as if it was an inflation hedge”, he blurted. “Soon it will overwhelm them to the point where it will be difficult to extract useful information from it and they will start ignoring it”.
When my friend first muttered these words, I thought he decided to leave the rewarding world of verification and become a political pundit. I was dismayed because I don’t like the term pundit, it rhymes with bandit. Ever wondered why we have verification gurus and they have political pundits? In any case, it turned out it was about a far less controversial kind of stimulus package, the one you feed to your design to tickle its inputs and make its transistors go crazy. Phew!
