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.
