This is a hardware implementation of the DCPU-16 cpu designed by @notch for his new game 0x10c.

It is entirely written in RTL level Verilog and is synthesisable. While functional, there is still plenty of room for improvements, optimisations etc.

Assumptions

You can simulate the files using Icarus Verilog. You should also install gtkwave as a waveform viewer, unless you already have something else to use.

If you do not have any of it installed, you will need to do that first. To do this in Ubuntu, simply issue:

$ sudo apt-get -y install iverilog gtkwave

Simulation

To simulate the DCPU16 RTL code, do the following from within the project directory.

$ cd sim/
$ ./iversim verilog/dcpu16_sim.v

This will dump out a LXT file that you can view with gtkwave:

$ gtkwave dump.lxt

That's it!

Have fun hacking!
