I've been working on changing the code so that it is synthesizable. I was originally planning on only simulating and so I took some shortcuts. I was loading the RAM while in reset, so I implemented the ROM and put the instructions in the declaration line instead. Then I took the clock and reset lines out.

Next up is making a chip-specific wrapper for my code. I grabbed the pin-constraints file for the Cmod board from the Digilent website. I need to make a few extra modules like the clock module and a reset. And I'll want to put a few extra features in there like halting the clock and stepping the clock manually. And I'll need to pass the RAM signals out of the chip, and then make the UART interface. Then it should work!
