WebThere are two types of procedural blocks in Verilog: initial : initial blocks execute only once at time zero (start execution at time zero). always : always blocks loop to execute over and over again; in other words, as the name suggests, it executes always. Example - initial Webrst = 1'b0; forever #10 clk = ~clk; end. This first block generates the clock and reset signals. You will use basically this exact same initial block for any test bench that is testing a sequential circuit. The clk and rst signals are initialized to 0 and 1 respectively. The next line uses the repeat statement. 17.
