WebA D flip-flop (DFF) is one of the most fundamental memory devices. A DFF typically has three inputs: a data input that defines the next state, a timing control input that tells the flip-flop exactly when to “memorize” the data input, and a reset input that can cause the … WebMay 24, 2013 · Sometimes the structural code has delays which make your behavioral code behave incorrectly. inital begin clk = 0; forever begin #5 clk = 1; #5 clk = 0; end end. Perhaps the #4 was used to release the rst just before the 1st clk edge at time=5. q <= #2 d; This is the clock-to-q delay.
