You don’t usually think of simulating Verilog code — usually for an FPGA — as a visual process. You write a test script colloquially known as a test bench and run your simulation.

There are many other cases where we see code duplication. “System Verilog Macro” is one of the many solutions to address such duplication. Such macro is very efficient and can help save a lot of time ...

("Is it working correctly?") They may also be used to provide functional coverage information for a design ("How good is the test?"). You can add assertions to your RTL code as you write it " these ...
