WebReset removal check: Removal check ensures that the deasserted reset signal does not get captured on the clock edge at which it is launched by reset synchronizer. For this, reset signal must be stable at lease " removal time " after the active clock edge. WebMar 4, 2008 · 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 …
