This is made for the [Digital Design and FPGA
workshop](FPGA_Workshop "wikilink") run in Fall 2009.
== makefile == Assumptions: You have iverilog, vvp and gtkwave in your
\$PATH. iverilog and vvp are the Icarus Verilog package. gtkwave is the
GTKWave+ package.

In order to use this makfile, the TOOL INPUT section must be modified to
match your needs. This involves the following

- Change the SRC macro to include your verilog source code files.
- Change the TESTBENCH macro to include your verilog testbench.
- Change the TBOUTPUT macro to the name of the file your dumping your
  testbench output too.


The posted makefile shows the TOOL INPUT macros pre-populated for
targeting an Arithmetic Logic Unit (alu).

    #   "make check" - compiles your verilog design - good for checking code
    #   "make simulate" - compiles your design+TB & simulates your design
    #   "make display" - compiles, simulates and displays waveforms

## convenient file copy script

Convenient file to copy the makefile from ~/resources/makefile to your
current directory. copy the script into a file, chmod +x the file and
place the file in your \$PATH. this assumes that ~/resources/makefile
does not have write permissions granted to it.

    #!/bin/bash

    #script it up!
    echo "Copying iVerilog makfile"
    if [ -r $fileofjustice ]; then
        cp $fileofjustice .
        chmod u+w ./makefile
        echo "makefile copied"
    else
