WebAug 16, 2024 · The next thing we do is generate a clock and reset signal in our verilog testbench. In both cases, we can write the code for this within an initial block. We then use the verilog delay operator to schedule the changes of state. In the case of the clock signal, we use the forever keyword to continually run the clock signal during our tests. WebThere are only two ways to change the value of parameter, 1. during instantiation of module, interface, program block or class.. or 2. using "defparam" statement. As we can not instantiate package, the first option won't work with package and the defparam statement works only with module, interface and program block.
