_.
LibSV is an open source, parameterized SystemVerilog digital hardware IP library. While similar libraries may already exist, LibSV is unique in that it takes advantage of open-source, state-of-the-art development best practices and tools from across the software and digital design community, including:
- Trivial installation.
LibSV is hosted on PyPI <https://pypi.org/project/libsv/>
_ and can easily be installed usingpip <https://pip.pypa.io/en/stable/>
_ or whichever Python package manager of your choice. - Easy-to-use. Simply add ```include "libsv/
/ / .sv" to where you want to use a LibSV module and then add the
site-packages/`` folder, where LibSV was installed, to the include path when building your project. - Automated testbenches, written in Python, that use
pytest <https://github.com/pytest-dev/pytest>
_ to runCocotb <https://github.com/cocotb/cocotb>
_ +Verilator <https://github.com/verilator/verilator>
_ under the hood for simple and fast logic simulation - All testbenches output waveform files in FST format for viewing with
GTKWave <http://gtkwave.sourceforge.net/>
_ -
Extensive documention <https://libsv.readthedocs.io/en/latest/>
_ usingSphinx <https://www.sphinx-doc.org/en/master/>
_ - Automated formatting and lint checks using
Verible <https://github.com/google/verible>
_ -
Continuous integration (CI) workflows <https://github.com/bensampson5/libsv/actions>
_ integrated withDocker <https://www.docker.com/>
_ -
LibSV Docker images <https://hub.docker.com/repository/docker/bensampson5/libsv>
_ published toDocker Hub <https://hub.docker.com/>

Getting Started
LibSV is very easy to use. First, install the libsv
package from PyPI:
.. code-block:: bash
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:
.. code-block:: SystemVerilog
`include "libsv/
Running Testbenches
Running the LibSV testbenches require Cocotb <https://github.com/cocotb/cocotb>
,
Verilator <https://github.com/verilator/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 <https://hub.docker.com/repository/docker/bensampson5/libsv>
__ that have the
complete set of LibSV developer tools already installed.
To use a LibSV Docker image, first you’ll need to install Docker <https://www.docker.com/get-started>
__,
if you don’t already have it.
Next, pull the latest LibSV Docker image:
.. code-block:: bash
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:
.. code-block:: bash
docker run --rm -it -v $(pwd):/code libsv
Finally, within the Docker container, run pytest
:
.. code-block:: bash
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:
.. code-block:: bash
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:
.. code-block:: bash
pytest -k EXPRESSION
Each testbench generates an associated .fst
waveform file that is written to the build/
directory and can be
viewed using GTKWave <http://gtkwave.sourceforge.net/>
