WebExample. Consider a simple verilog design of a D-flip flop which is required to be verified. The functionality of DFF is that Q output pin gets latched to the value in D input pin at … 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 ...

WebAs a first trivial introduction to cocotb, the following example "tests" a flip-flop. First, we need a hardware design which we can test. For this example, create a file dff.sv with SystemVerilog code for a simple D flip-flop.
