Looking for help with writing test cases.

Howdy.

I am trying to test a RAM module by storing randomly generated values into it and then reading them back out. There are 16 addresses, each of which can store 4 bits. I want to generate the values, store them all into the RAM, and then check them all; however, I do not know the best way of doing this. I have looked at the included documentation, but I was wondering if this is based on a language I can look for on the web.

Is there a way to make arrays? Also, is there a way to get the last 4 bits of a value to check it against an output? (I am aware of the 'bits' function, but I believe that this splits it up so that I could check 4 1-bit outputs, not 1 4-bit output.)

Thanks for any help, and I would be happy to include an example file if that would be helpful.

Arrays cannot be used. So you have to use computable values that depend on an index. But this is not significantly worse than random values.
