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. 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 ...
