Hi Guys,
So I've implemented my ALU to my satisfaction, i.e. it passes my little test script OK, but I was wondering if there is a corpus of test scripts with corresponding compare files against which I could do some additional testing? I'm just concerned about the very large number of different input combinations (2^38 by my reckoning) and the difficulty of ensuring I've got a design with no subtle errors.
I do note that the book mentions scripts on the web site - but I couldn't find them
. Feel free to point me in the right direction, or alternatively... anyone care to share some meaty test/compare files?
Thoughts on effectively testing non-trivial chip designs also gratefully received :)
