The file trycpu contains a C shell script for testing
your project 3 solutions.  It assumes you have prepared files whose names
end in ".text", ".data", and ".dump" and start with the same prefix.
For example, the files
    lw.sw.test.text
    lw.sw.test.data
    lw.sw.test.dump
in the test folder follow this convention and all have prefix "lw.sw.test".
It also assumes that you have compiled your Verilog source, producing
a file that can be run with the "vvp" command. 

To use the shell script, copy it to your directory and then type
    trycpu prefix
or
    trycpu vvp_file prefix
where vvp_file is the name of your compiled Verilog program and prefix
is as described above.  For example, to test your program on the lw/sw
test in the test folder, you might say
    trycpu lw.sw.test

The shell script will copy your test files to "text.dat" and "data.dat",
run your simulation, and compare the "dump.dat" file it produces with
your test .data file.
