WebAug 26, 2024 · Tom would go on to create PrimeTime, which was the standard timing signoff tool for foundries for some time. Cadence then got serious about producing an industrial-strength timing signoff tool aimed at the largest designs running the largest datacenters. Tempus was released in 2013. WebAs long as you and your company believe in and use the corner-based signoff, you practically need to close timing at all conceivable corners, at least, at final stage of the …
WebSep 9, 2024 · Aging Aware Timing Analysis Approaches. Traditional Aging-based static timing techniques rely on derate methodology. In this method, the cycle time used during design timing closure would be multiplied by a conservative aging factor and released with the reduced frequency spec – i.e., a “guardband” approach.
