Web5 Aug 2024 · As the purpose of the setup timing check is to make sure that data should reach the input pin of the register prior to the clock edge, the purpose to check hold … Web4 Mar 2008 · Activity points. 1,443. clockgating. Clock gating is basically done to reduce the switching power of a flop. The circuit is like a flop in which its clock input is gated using an And gate. the other input to the and gate is a control signal. you can see in the figure. I don't think this changes the timing of the chip.
