Thanks to the "HDL Survival Guide > Tests Are More Than Pass/Fail" I was able to isolate the chip parts - minus the zr, ng outputs.

I created copy of ALU.tst > ALU-MY.tst

I created a new output file > ALU-MY.out

I then edited my ALU-MY.tst
- Changed output-file to ALU-MY.out
- Commented out the compare-to ALU.cmp line.

Now I am able to test the non zr, ng parts.

Looking at my output file, some outputs are correct and some aren't. I've double, triple and quadruple checked my pins, etc. I need some help.

Thanks in advance for your help.
