Concurrency adds complexity for which the industry lacks appropriate tools, and the problem has grown to the point where errors can creep into designs with no easy or consistent way to detect them.
Time spent in verification has grown, and it will continue to grow because of this. “In complex chip designs, finding corner-case bugs is a critical part of the functional verification process,” says Tom Anderson, technical marketing consultant for OneSpin Solutions. “Corner-case bugs, in turn, are all about concurrency. They occur when specific combinations of events happen at the same time and trigger behavior not previously exercised.”
