WebA clock enable is usually prefered to a gated clock, because a gated clock can cause timing violations, see Timing Diagram. But a gated clock completely "turns off" the clock for a part of the design, and therefore … WebFeb 27, 2014 · 291,745. Re: "gated clock" warning, what is the solution for my code? The warning seems to miss the problem. I presume you want to make a pure combinatorial MUX but you generate a latch because select isn't fully decoded, pDATAOUT is hold for two input sSELECT codes. You'll want to select a default output value and code it respectively.
In computer architecture, clock gating is a popular power management technique used in many synchronous circuits for reducing dynamic power dissipation, by removing the clock signal when the circuit is not in use or ignores clock signal. Clock gating saves power by pruning the clock tree, at the cost of adding more logic to a circuit. Pruning the clock disables portions of the circuitry so that the flip-flops in them do not have to switch states. Switching states consumes power. When not b… WebDec 24, 2015 · Active-low clock gating check: Occurs when gating cell has an or or a …
WebJul 29, 2015 · I have a 1-bit signal coming from a part of my circuit that is running on a 40 MHz clock. The signal is mostly 0, except it is 1 for a single 40 MHz-cycle every ~million cycles. Another part of my circuit is running on a 1 MHz clock. I would like to do some synchronous processing on the signal described above in this part of my circuit.
