WebApr 12, 2024 · 2. In verilog, when you are instantiating a module, that means you are adding extra hardware to the board. This hardware must be added before simulation starts (i.e. at compile time). Here, you can not add/remove hardware at each clock pulse. Once instantiated, the module is executed/checked for each timestamp of simulation, till the end.
