I have been dabbling with this approach with various mechanisms (file based/ array based etc). The scalability of this approach for larger designs and achieving cross coverage is tricky

Perhaps I have misunderstood, but isn't there a danger with what you're suggesting that you test a design to check it does what it should, but you're not checking to see that it doesn't do what it shouldn't? I can think of a couple of things that caught us out over the years where I thought - I wonder if random testing would have spotted that?

Most of the time you will set constraints to ensure that only valid inputs are chosen by constrained random, but you can send in bad data as well to see if it is handled correctly. What I am more concerned about is that you don't actually test anything at all, you just create a false illusion that you are.

Of all the exhibits in the Pre-Apocalypse Era Museum, Breek was always in awe of the unearthed details and true-to-scale reproduction of a technological creation space that the long gone humans had once inhabited.
