Other timing analyzers support OCV but apply a single derating factor to all timing paths, said Arthur Wei, vice president for operations at Incentia.That can extend path delays by 20 percent, he said.
TimeCraft's OCV uses variable derating factors that minimize delay overhead, Wei said, so "you see fewer timing violations in your timing report.You can fix timing . . . and achieve timing closure" more easily.
The variable derating takes both logic levels and location into account.Each path can be given a different derating factor.
TimeCraft does not have a multiple-corner capability, but it does offer multitasking, Wei said.
