Web4 de dez. de 2009 · In our designs we normally implement a hierarchical clock-gating technique that puts multiple levels of clock-gating cells in the design. The multiple levels also exist because clocks from the various sources (PLL, external oscillator, dividers) get distributed throughout the chip via a clock-distribution network that generates gated and …
WebBenefits of Clock Gating: 1) Dynamic Power savings. 2) Eliminating multiplexers saves area. In earlier designs we used to use multiplexer for each register which consumes lot of area if we have to implement multiplexer for every register. 3) Easy to implement - no RTL code change is required.
