Has simulation performance stagnated, and what is the industry doing to correct it?
Without functional simulation the semiconductor industry would not be where it is today, but some people in the industry contend it hasn’t received the attention and research it deserves, causing a stagnation in performance. Others disagree, noting that design sizes have increased by orders of magnitude while design times have shrunk, pointing to simulation remaining a suitable tool for the job.
“Simulation will always miss corner case bugs,” says Rob van Blommestein, head of marketing at OneSpin Solutions. “Even if multiple simulation runs are employed, bugs can escape. Formal not only provides exhaustive verification to ensure that critical corner case bugs are detected, but also allows for comprehensive coverage of the entire design. Using formal early in the design and verification process, will relieve pressure on the simulation runs so that simulation can focus on non-corner case issues.”
