WebAug 27, 2024 · To solve the setup violation, tool is adjusting the launch and capture path in such a way that the launch clock path plus data path delay is reduced and capture path delay is increased. The overall clock buffer and inverter count is less than the default experiment. Hence the power consumption and area is reduced. 3) Appling NDR WebOct 11, 2015 · Clock gating is a popular technique used in many synchronous circuits for reducing dynamic power dissipation. Clock gating saves power by adding more logic to a circuit to prune the clock tree. 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.
