pynqutils 0.1.1

Utilities for PYNQ

version 0.1.1

PYNQ-Utils is a repository containing utilities used in various other repos and projects across the PYNQ ecosystem. The tools are categorized into three sections:

• /runtime for utilities that are used in the PYNQ runtime, such as ReprDict which is used to pretty print dictionaries in Jupyter.
• /setup_utils for utilities that are used in the construction of python packages and to help in managing the PYNQ environment.
• /build_utils for utilities that are mainly used at build time when constructing Overlays. However, there are some utilities here that overlap with other sections, such as the XSAParser, which is also used by the PYNQ runtime for parsing the design metadata and bitstream.

QuickStart

To install PYNQ-Utils use the following command:

python3 -m pip install pynqutils 

setup.py example

One place where PYNQ-Utils is frequently used is in the setup.py of projects that build upon PYNQ.

from pynqutils.setup_utils import build_py, find_version, extend_package, get_platform

data_files = []
extend_package(path=os.path.join(module_name, "notebooks"), data_files=data_files)

setup(
    name="pynq_helloworld",
    version=find_version('{}/__init__.py'.format("pynq_helloworld")),
    description="PYNQ example design supporting edge and PCIE boards",
    long_description="PYNQ HelloWorld example design",
    long_description_content_type='text/markdown',
    author='Xilinx PYNQ Development Team',
    author_email="[e-mail]",
    url='https://github.com/Xilinx/PYNQ-HelloWorld.git',
    license='BSD 3-Clause License',
    packages=find_packages(),
    package_data={
        "": data_files,
    },
    python_requires=">=3.6.0",
    install_requires=[
        "pynqutils",
        "matplotlib",
        "ipython"
    ],
    entry_points={
        "pynq.notebooks": [
            "pynq-helloworld = {}.notebooks.{}".format( "pynq_helloworld", get_platform())
        ]
    },
    cmdclass={"build_py": build_py}
)

As can be seen from the above snippet PYNQ-Utils contains lots of handy utilities for creating a setup.py script. Some examples from above are:

• find_version - used to find the verstion of the current project from the source
• extend_package - used to search directories to find files and directories to add to the package.
• get_platform - used to determine the current platform that the project is being installed onto, for instance, edge or pcie.

A complete example of a setup.py using PYNQ-Utils can be found here.
