WebUsing the one-hot launch-on-shift approach, a launch clock pulse followed by a capture clock pulse are applied to only one clock domain during each capture window, while all other test clocks are held inactive. An example timing diagram is shown in Fig. 2. It applies shift-followed-by-capture pulses (S1-followed-by-C1 or S2-followed- Web23 feb. 2024 · The launch clock path and the capture clock path share a portion of the clock tree (B1, B2) and then diverge from the common point. This common path delays are multiplied with different derates (early and late), resulting in different delays. These cells have max delay in launch path and min delay in capture path.
