Clock – A signal with constant rise and fall with ideally equal width (50% rise and 50% fall of the signal width) helps to control data propagation through the clock elements like Flip-Flop, Latches etc. The clock source mostly present in the top-level design and from there propagation happens. PLL, Oscillator like …
WebNov 12, 2015 · In the picture, the clock of valid_event_buf_reg [10] is from an ICG cell (red cell), but in the timing report, the capture clock path only take clock uncertainty into account, no ICG delay. I didn't use clock gating before, I don't how to make constrain on it, especially for the coded ICG cells. Anybody can help. Thank you Nov 5, 2015 #2 S
