Verification's Inflection Point
By: Brian Bailey
What will the future of verification look like? New demands being placed on verification teams are causing the industry to take a deep look at the possibilities.
Verification no longer ends when chips or products are shipped. “We must take a holistic approach to verification when we talk about continuous verification throughout the product lifecycle,” says Rob van Blommestein, head of marketing for OneSpin Solutions. “We need to look at solutions that work to verify not only functional behavior but also safety and security aspects, and simulation alone cannot be the answer. Formal should be an integral part of the verification puzzle if proper verification closure is to be met. It is incumbent that design teams plan early for verification so that specific bugs, including corner-case bugs, can be detected before it is too late, and delays occur. Design and verification teams ought to work closely with safety engineers and security engineers to make this happen.”
Verification has been under pressure for a long time. Miraculously, chip failure rates have not increased significantly over time. This means the tools and flows that exist today, while not perfect, are doing an adequate job.
However, we should never stop looking for better solutions. Continuing in the same direction that we have been going is raising new environmental concerns, and additional demands being placed on the verification team are beginning to muddle the responsibilities between teams. The industry is increasingly looking at ways we could be doing it better, and it is not yet clear what the future looks like.
