Re: Clock Gating. It is basically used to save the Dynamic Power in the design. Clock gate can consist of some gate (AND/OR/NOR/NAND) and a latch. This is called discrete clock gating. It may be present in the library as a single entity.That is called Integrated Clock Gating. WebPLL clock (pll_clk) or fast clock (fast_clk) is output from the PLL circuit. It is a multiplied reference clock and also works at free-running state. It is used for generating the launch and capture pulse when the scan enable signal is low. The slow clock (slow_clk) is from the automatic test equipment (ATE). So it is also called ATE clock (ate ... bipolar disorder air force
