Iverilogmakefile
From HacDC Wiki
This is made for the Digital Design and FPGA workshop run in Fall 2009. <br>
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.
<br> The posted makefile shows the TOOL INPUT macros pre-populated for targeting an Arithmetic Logic Unit (alu). <pre>

- 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
-
- CHANGE THESE THREE LINES FOR YOUR DESIGN
- TOOL INPUT
SRC = alu.v alu_func.v alu_regn.v dff.v TESTBENCH = alu_tb.v TBOUTPUT = waves.lxt #THIS NEEDS TO MATCH THE OUTPUT FILE #FROM YOUR TESTBENCH
- BE CAREFUL WHEN CHANGING ITEMS BELOW THIS LINE
- TOOLS
COMPILER = iverilog SIMULATOR = vvp VIEWER = gtkwave
- TOOL OPTIONS
COFLAGS = -v -o SFLAGS = -v SOUTPUT = -lxt #SIMULATOR OUTPUT TYPE
- TOOL OUTPUT
COUTPUT = compiler.out #COMPILER OUTPUT
- MAKE DIRECTIVES
check : $(TESTBENCH) $(SRC) $(COMPILER) -v $(SRC)
simulate: $(COUTPUT) $(SIMULATOR) $(SFLAGS) $(COUTPUT) $(SOUTPUT)
display: $(TBOUTPUT) $(VIEWER) $(TBOUTPUT) &
- MAKE DEPENDANCIES
$(TBOUTPUT): $(COUTPUT) $(SIMULATOR) $(SOPTIONS) $(COUTPUT) $(SOUTPUT)
$(COUTPUT): $(TESTBENCH) $(SRC) $(COMPILER) $(COFLAGS) $(COUTPUT) $(TESTBENCH) $(SRC) </pre>
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.
