HW1Part2

system requirment

OS tested: macOS Ventura 13.1

It should theoretically be fine with older macOS versions as well (Monterey, BigSur, Catalina).

Some things are here for the sake of completion. Skip any step if you already have it, eg. I expect most people using macOS already have homebrew.

Install homebrew

Link: https://brew.sh

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

Install verilator

Homebrew Link: https://formulae.brew.sh/formula/verilator

brew install verilator

Please check homebrew link for any dependencies you may need.

Install the GTKwave

Homebrew Link: https://formulae.brew.sh/cask/gtkwave

brew install --cask gtkwave

Please check homebrew link for any dependencies you may need.

Ready to run?

Step 0: go back to parent directory and then download the testing file from repo

cd ~
git clone https://github.com/gt-cs3220/gt-cs3220.github.io

Step 1: compile the verilog module of adder_var_seq.

cd gt-cs3220.github.io/Spring_2023/hw1part2/
verilator --cc adder_var_seq.v --top-module adder_var_seq

Step 2: Create the Cpp simulation file for Verilator. Pls take a look at the adder_var_seq.cpp in the current folder. The detail explainations are listed inside the adder_var_seq.cpp.

Step 3: Compile the executable file

verilator -Wall --trace --exe --build -cc adder_var_seq.cpp adder_var_seq.v

Step 4: Run the executable file. Inside obj_dir there should be a Vadder_var_seq executable. Run it.

./Vadder_var_seq

Step 5: Open the GTKWaver to open the generated trace open “GTKWaver” -> “Open New Tab” -> “Select the generated waveform.vcd” -> “click on Top” -> “Right click the signals below” -> “Recurse Import” -> “Append” Then all waveforms will show up in the Waves window.
