Part 2: Formal Verification Program Leader: The Critical Role of Planning and Measurement

Tuesday, May 17th, 2016

As in any engineering endeavor, formal verification involves engaging individuals in many different roles, often including formal managers and, given the technically deep and complex nature of FV, nearly always one or more formal experts. The manager of the formal verification effort on a project may have formal as his or her primary or sole responsibility, or may manage multiple aspects of verification (e.g. both simulation and FV). However, even a full-time formal verification manager may or may not drive the overall formal program in their company or organization.

In part one of this discussion, I talked about the emerging role of the Formal Verification (FV) Program Leader, an individual who enables and drives the formal process by navigating organizational dynamics, understanding designs and their verification complexities and schedules, developing and presenting ROI trade-offs, etc.; all to help achieve project goals. I listed six aspects of this role that the FV Program Leader must master in order to effectively lead the adoption and deployment of formal verification: Organization, Training and Upskilling, Test Planning, Progress Metrics, Sign-off Process, and Post Mortem Analysis.

Achieving Formal Sign-off: Key Learnings for Trainees and Experts

Monday, May 2nd, 2016

Formal sign-off is possible with today’s technology and methodology. But to get to formal sign-off takes an understanding of what is possible with formal verification, and an immersion in ongoing practice with formal methods and techniques. Moreover, early experiences with formal can determine later success with formal verification and sign-off. Even with a deep knowledge of a formal verification tool and extensive training from the tool vendor, exponential formal proof complexity often gets in the way of exhaustive coverage. Often what is needed is training in formal verification methodology and formal test planning that includes an exhaustive list of end-to-end checkers, as well as the mastering of formal techniques that help overcome complexity.
