WebJan 20, 2015 · Think of a clock gate as "simple and" with an enable gating the clock. The reason you do this is to stop unnecessary toggles on the clock pin of flops. Even if the output doesn't toggle, the internal flop circuitry dissipates unnecessary power. Power saving can be achieved by simply gating the clock with an enable. WebClock gating is a power-saving feature in semiconductor microelectronics that enables switching off circuits . Many electronic devices use clock gating to turn off buses , … ne portland or hotelsWebMar 8, 2024 · Summary. Classic clock gating can significantly reduce power consumption. This can be done, for example, by switching off the clock signal for DFFs that don’t change state. For a synchronous system in which the logic is driven by the rising edge of the clock, we should use an OR gate to generate the gated clock. ne portland things to do

"WebClock gating checks are inferred for the two AND gates, but not for the OR gate. This is because although both CLK1 and CLK2 arrive at the OR gate, both are consumed as clocks downstream. PrimeTime therefore understands that both of these are clock signals being steered and combined with logic, and no gating check is inferred. " - Clock gating checks
