* Each file contains its own testbench program.
* To test the whole CPU use cpumips02-cpu.v
* The reference program is a 15-instruction assembly program mipstest.s
* The program mipstest.s is assembled for the verilog in the file memfile.dat
* These file were tested with "Verilogger Pro 6.5e" which is freely available 
  and distributle in a trial version: this is a very simple to install
  verilog simulator for Windows
