WebFor example, maybe the max tran for the design is 900 ps, but for my clocks I want 400 ps. This is specified in the clock spec file: The report generated after CTS will show if these transition limits were met. Even if they violate slightly, we usually move on because we know the transition is tight in the first place. WebThe middle section consists of the clock path delay and the data path delay.

WebPhysical Design Q&A. Q41. Why do we emphasize on setup violation before CTS and hold violation after CTS? Setup time of a valid timing path depends on: Max data network computation time vs clock edge arrival time at the sink. Until POST CTS stage, we assume all clocks as ideal networks and it could reach in 0 time to every possible clock sink ...
