第一，设置clock gating check比较麻烦。第二，不利于timing signoff，容易遗漏实际需要gating check的点，出现glitch。现在大部分都是集成的ICG (Integrated Clock Gating )。2.Place阶段ICG使能端的Setup violation place过程data path优化力度不够。出现这种情况，一方面可以在DCT中设置一个稍微大点的gating check，并...
The method also includes passing the latched logic value of the enable signal to a clock-gating output when the input clock signal is logically high, blocking the latched logic value of the enable signal from the clock-gating output when the input clock signal is logically low, and pulling ...

A low-power low-setup integrated clock gating (ICG) cell is disclosed. The disclosed ICG cell includes a NOR gate configured to receive an enable (E) signal and a test enable (SE) s
The latch module is configured to cause the internal enable node to transition from low to high as a function of the enable module output and C, where E is the internal enable node and C is the clock.RASOULI Seid HadiDILLEN Steven James...

The latch module is configured to cause the internal enable node to transition from low to high as a function of the enable module output, the internal enable node and the clock.RASOULI, SEID HADIDILLEN, STEVEN JAMESDATTA, ANIMESH
A setup time of a single device propagation delay is provided for a received enable signal. When each of a clock signal, the enable signal and a delayed clock signal is asserted, an evaluate node of the clock gating circuit is discharged. When each of the clock signal and a second clock...
