What is this

A simple Verilator and Verilog project setup for testing a timer (timer_thing.sv). Use this project as a template and starting place for your own Verilator projects!

Setup

• Follow the steps at the bottom to install Verilator and Gtkwave
• clone this repo, and type make and then make show

Running

• use make to recompile all verilog and run
• use make quick to only recompile test-bench cpp files (ignoring any verilog changes) and run
• use make show to show your output
• use make clean to delete all output files

See hdl/timer_thing.sv

Example Output

gtkwave

Used to view wave files. Install with

sudo apt-get install gtkwave

Verilator

This is an opensource simulator for verilog. You need to have verilator installed (I'm on ubuntu). Verilator must be installed to /usr/local/share/verilator in order for the make scripts to work

sudo apt-get install flex bison autoconf libfl-dev gdb build-essential

cd
git clone http://git.veripool.org/git/verilator
