WebSep 3, 2012 · Very simple. There is no problem in using the clock signal as select input for multiplexer. Mux operation depends on the clock value at that instant of time. This is also known as Time Division Multiplexing. (TDM) eg: Consider a 2to1 Mux. When clock signal (Select S) is '0' the the first input (a) comes out of the MUX and when it goes to '1 ... WebOct 13, 2024 · Synthesis sees this type of description as a perfect candidate for clock gating. If the data input to a flip-flop can be reduced to a MUX between the data pin and the output pin of the flip-flop, the synthesis tool can model this flip-flop by connecting the “data input” directly to the data pin of the flip-flop, and by using the MUX enable to gate the …
