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. 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.
