Iverilogmakefile

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.

This is made for the Digital Design and FPGA workshop run in Fall 2009.

# USE THE FOLLOWING COMMANDS WITH THIS MAKEFILE
#	"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
