OCV, AOCV and POCV in VLSI : A comparative analysis

WebPOCV stands for Parametric On-Chip Variation. POCV was proposed to address shortcomings of AOCV/SBOCV for granularity, accuracy, Common path pessimism removal and half cycle paths. POCV eliminates the need for stages, path type and corner delay to find delay derate during characterization phase. It pushes these steps in to static timing ... WebThe challenge of CPPR is that the amount of pessimism to be removed is path-dependent. Existing solutions fall into two categories, critical-path-based approach and exhaustive search approach. The critical-path-based approach first identifies critical paths without CPPR consideration and then re-evaluates these identified paths with CPPR.

WebCRPR and Crosstalk Analysis. When you perform crosstalk analysis using PrimeTime SI, a change in delay due to crosstalk along the common segment of a clock path can be pessimistic, but only for a zero-cycle check. A zero-cycle check occurs when the same clock edge drives both the launch and capture events for the path.
