Coverage driven verification has a big advantage – you can write a single test, and let run it several times with random seeds. Each run will generate a slightly different scenario – depending on the nature of the constraints you provided. I’ve talked about the pros and cons of excessive use of coverage driven methods here and here. Anyway, sometimes you just want to take an existing test and quickly create a number of variants off of it to make a small regression suite (that you might even throw away later on). For example – you could have a basic test that does some CPU writes and then drives random frames. During configuration you write to a register that sets the FIFO level and you want to have 10 different tests, each writes a different value to this register.
