Re: Quartus II clock gating methodology - Intel Communities

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. Clock gating is automatically inserted by the tool. Web11-13-2013 11:50 PM. Well, it seems to work for you, so take the following with a grain of salt. On FPGAs, any kind of logic generated clock tends to have skew issues. The two possible approaches to clock gating are (in Altera terms): a) use the ALTCLKCTRL that sits atop the clock distribution trees b) use the clock gating logic in each LAB.
