WebbSystemVerilog has a number of methods to generate pseudo-random numbers - $random, $urandom, $urandom_range, object.randomize, std::randomize and many more. We look at how these methods are different and when to use each of them. All code presented here can be downloaded from GitHub.

WebbThe advantage of random logic is that it avoids the overhead of fetching the microcode from it's storage.
