WebIn 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 … http://www.ispd.cc/slides/2013/7_dangat.pdf

WebClock Gating在后端会引起一些问题，尤其在Setup Timing以及时钟树综合阶段，有时候会需要做一些特殊的处理。关于为何Clock Gating容易引起setup timing 的问题，请参考本专栏的文章【后端Timing基础概念之：为 … WebThere is one main clock that supplies the design. This main clock (from a PLL) is split into two clocks - one that´s always running and one with a clock gate. This is to turn off some parts of the design to save power. So, it roughly looks like this: cpu_clk = main_pll_clk_out; gated_cpu_clk = main_pll_clk_out & enable; cryptogenic stroke anticoagulation
