WebNov 14, 2024 · When clock (CLK) input is high, whereas R value is 0 and value of S is 1 (i.e. CLK = 1, R = 0 and S = 1), in such a situation, flip-flop tends to set (i.e. flip-flop output Q turns out to be high or 1) owing to gate number 3 output being 0 but gate number 4 … WebThere is one main clock that supplies the design. This main clock (from a PLL) is split into two clocks - one that´s always running and one with a clock gate. This is to turn off some parts of the design to save power.

Consider the circuit shown above. If the input R is at logic level “0” (R = 0) and input S is at logic level “1” (S = 1), the NAND gate Y has at least one of its inputs at logic “0” therefore, its output Q must be at a logic level “1” (NAND Gate principles). Output Q is also fed back to input “A” and so both inputs to NAND gate X are at logic level “1 ...
