Formal verification of hardware designs has been around for more than 25 years. Commercial tools, for example from AT&T Bell Labs and IBM, started appearing in the 1990s. It’s only recently that formal verification has been adopted into design and verification flows, due to a number of reasons. It’s harder to learn than simulation or emulation because of its complexity, and it takes time for a verification engineer to become proficient in using it. Formal verification experts typically learn 100s of different techniques over the course of their careers.
Now that we are in the era of formal verification, an important new role is emerging –– the Formal Verification Program Leader (FV Program Leader). (more…)
