Getting Started

LibSV is very easy to use. First, install the libsv package from PyPI:

pip install libsv

We recommend using a Python virtual environment so that the installation is project-specific and isolated from the rest of your system.

Then add the site-packages/ folder, where LibSV was just installed, to your include path when building your project so that your design tools can find LibSV.

Finally, at the top of your design file where you want to use LibSV modules, for each module you want to use, add:

`include "libsv/<path>/<to>/<module>.sv"

Running Testbenches

Running the LibSV testbenches require Cocotb, Verilator, and a number of other dependencies to be installed. Instead of trying to install everything manually on your machine, the easier and recommended way to run the LibSV testbenches is to use the pre-built LibSV Docker images on Docker Hub that have the complete set of LibSV developer tools already installed.

To use a LibSV Docker image, first you’ll need to install Docker, if you don’t already have it.

Next, pull the latest LibSV Docker image:

docker build --pull -f Dockerfile.dev \
  --build-arg UID=$(id -u) \
  --build-arg GID=$(id -g) \
  -t libsv .

Then, start a new Docker container using the LibSV image and mount the project folder to the container:

docker run --rm -it -v $(pwd):/code libsv

Finally, within the Docker container, run pytest:

pytest

This will run all the LibSV testbenches for the entire library (Warning: This may take a while!).

Instead, to list all the available LibSV testbenches, run:

pytest --co

Then, you can run an individual or subset of testbenches using the -k flag which will only run tests which match the given substring expression:

pytest -k EXPRESSION

Each testbench generates an associated .fst waveform file that is written to the build/ directory and can be viewed using GTKWave.
