Insert clock gating except subdesign synopsys
WebUsing the enable scorecard, it is easy to analyze different blocks for clock activity and learn how much more clock gating is possible to reduce the activity. For example, the design … WebActive clock gating is based on the following concepts: 1) If an FSM is in non-functional states then the logic related to that part of design is inactive. 2) If all the FSMs in a clock domain are in non-functional states then the logic in that domain is inactive.

This is done with the following command: create clock Clk CI -period 6.0 With this command, we have created a clock on the port Clk CI of our RegisteredAdd design, with a period of 6.0ns. Note that the command does not specify the time units; these are defined by the technology library being used.

WebDec 17, 2012 · Dec. 17, 2012. Clock gating is one of the most frequently used techniques in RTL to reduce dynamic power consumption without affecting the functionality of the design. One method involves ... Webaggressive clock gating and analysis of target technologies without the need to lower the voltage levels of specific portions of the design (multi-voltage). If a only a single voltage level is necessary, but using a power-down portion of the design is desired, this is known as a multi-supply design. This is an attractive design model for our goals.
