WebMay 8, 2024 · D flip-flop with asynchronous reset Specification. One of the most useful sequential building blocks is a D flip-flop with an additional asynchronous reset pin. When the reset is not active, it operates as a basic D flip-flop as in the previous section. When the reset pin is active, the output is held to zero. Typically, the reset pin is active ... WebFirst, reset is driven to 1 to reset the flop, while d is driven with an X: clk = 0; reset = 1; d = 1'bx; From the console display, we see that the flop has been properly reset with q == 0. Reset flop. d:x, q:0, qb:1. Next, reset is released, while input d is driven to 1: d = 1; reset = 0; The output q remains at 0 because the design did not ...
