Or16 Comparison failures. I can't figure out what I'm doing wrong.

[Stujo]

I've been banging my head against the wall all day. I even looked up the answer, which matches mine. Am I missing something? Or is there something wrong outside of the PARTS section (corruption of the .hdl or error in .tst file)?

Well, let's look at what the output and comparison files tell us.

Line 4
| 1111111111111111 | 1111111111111111 | 0000000000000000 | (from out)

Looks like your OR gate is acting like and XOR gate.

Go back and verify that it is working properly.

Thanks, my Or gate is essentially an Xor gate, hence my Or16 is as well. I thought I had tested it successfully, but at least I know what to do now.

Glad you got it fixed. Even better, you learned a little bit more about debugging.

And thanks for deleting your code out of your original post -- that's just the way to do it.
