<p>To begin using F4PGA, you might want to take a look at the <a class="reference internal" href="#gettingstarted-guidelines"><span class="std std-ref">Guidelines</span></a> below, which make for a good
|
|||
|
|
starting point.
|
|||
|
|
They will guide you through the process of installing and using the flows, explaining how to generate and load a
|
|||
|
|
bitstream into your FPGA.</p>
|
|||
|
|
<p>F4PGA flows are composed of multiple tools, scripts and CLI utilities.
|
|||
|
|
Fortunately, various alternatives exist for setting up the whole ecosystem without going through the daunting task of
|
|||
|
|
installing pieces one-by-one.
|
|||
|
|
See <a class="reference internal" href="#gettingstarted-toolchaininstallation"><span class="std std-ref">Toolchain installation</span></a> below.</p>
|
|||
|
|
<section id="guidelines">
|
|||
|
|
<span id="gettingstarted-guidelines"></span><h2 id="guidelines">Guidelines<a class="headerlink" href="#guidelines" title="Link to this heading">¶</a></h2>
|
|||
|
|
<p>This is the main documentation, which gathers info about the <a class="reference internal" href="f4pga/index.html#pyf4pga"><span class="std std-ref">Python CLI tools and APIs</span></a> and the
|
|||
|
|
<a class="reference internal" href="flows/index.html#flows"><span class="std std-ref">Design Flows</span></a> supported by F4PGA, along with a <a class="reference internal" href="glossary.html#glossary"><span class="std std-ref">Glossary</span></a>, references to specifications, plugins and
|
|||
|
|
<a class="reference internal" href="references.html#references"><span class="std std-ref">publications</span></a>.</p>
|
|||
|
|
<p>Since F4PGA is meant for users with varying backgrounds and expertise, three paths are provided to walk into the ecosystem.</p>
|
|||
|
|
<p><strong>Newcomers</strong> are invited to go through <a class="reference external" href="https://f4pga-examples.readthedocs.io">Examples ➚</a>, which provides
|
|||
|
|
step-by-step guidelines to install the tools through <a class="reference external" href="https://conda.io">Conda ➚</a>, generate a bitstream from one of the
|
|||
|
|
provided designs and load the bitstream into a development board.
|
|||
|
|
See <a class="reference external" href="https://f4pga-examples.readthedocs.io/en/latest/customizing-makefiles.html#customizingmakefiles" title="(in F4PGA examples)"><span>Customizing the Makefiles</span></a> for adapting the build plumbing to your own desings.</p>
|
|||
|
|
<p>For <strong>Intermediate</strong> users and contributors, who are already familiar with installing the tools and building bitstreams,
|
|||
|
|
it is recommended to read the shell scripts in subdir <a class="extlink-ghsrc reference external" href="https://github.com/chipsalliance/f4pga/blob/main/scripts">scripts</a>, as well as the Continuous Integration

|||

|

|
<p>F4PGA flows require multiple radpidly moving tools, assets and scripts, which makes it difficult for system packagers to
|
|||
|
|
catch up.
|
|||
|
|
Although some of the tools used in F4PGA (such as yosys, nextpnr or vpr) are available already through <code class="docutils literal notranslate"><span class="pre">apt</span></code>, <code class="docutils literal notranslate"><span class="pre">dnf</span></code>,
|
|||
|
|
<code class="docutils literal notranslate"><span class="pre">pacman</span></code>, etc. they typically use pinned versions which are not the latest.
|
|||
|
|
Therefore, the recommended installation procedure to follow the guidelines in F4PGA is repositories is using <a class="reference external" href="https://conda.io">Conda ➚</a>,
|
|||
|
|
or some other pre-packaged solution combining latest releases.</p>

|||

|
|||
|
|
<p>Due to size constraints, Architecture Definition packages cannot be distributed through Conda.
|
|||
|
|
Hence, installing a functional F4PGA system is a two step process: bootstraping the conda environment and getting the
|
|||
|
|
tarballs (or vice versa).
|
|||
|
|
In the future, getting and managing the tarballs might be handled by F4PGA.</p>
|
|||
|
|
</div>
|
|||
|
|
<p>In coherence with the <a class="reference internal" href="#gettingstarted-guidelines"><span class="std std-ref">Guidelines</span></a> above, multiple Conda environments are provided:</p>
|
|||
|
|
<ul class="simple">
|
|||
|
|
<li><p><strong>Newcomers</strong> will find environment and requirements files in <a class="extlink-gh reference external" href="https://github.com/chipsalliance/f4pga-examples">gh:chipsalliance/f4pga-examples</a>, which are to be used

as explained in <a class="reference external" href="https://f4pga-examples.readthedocs.io/en/latest/getting.html#getting" title="(in F4PGA examples)"><span>Getting F4PGA</span></a>.</p></li>
|
|||
|
|
<li><p><strong>Intermediate</strong> users and contributors can use the minimal environment and requirements files included in the
|
|||
|
|
Architecture Definition packages, as is done in the CI of this repository.</p></li>
|
|||
|
|
<li><p><strong>Advanced</strong> users and developers will get all the dependencies by bootstraping the environment in <a class="extlink-gh reference external" href="https://github.com/SymbiFlow/f4pga-arch-defs">gh:SymbiFlow/f4pga-arch-defs</a>.</p></li>
|
|||
|
|
</ul>
|
|||
|
|
<p>Summarizing, the installation procedure implies:</p>
|
|||
|
|
<ul class="simple">
|
|||
|
|
<li><p>Setting environment variables <code class="docutils literal notranslate"><span class="pre">F4PGA_INSTALL_DIR</span></code> and <code class="docutils literal notranslate"><span class="pre">F4PGA_FAM</span></code> (and optionally <code class="docutils literal notranslate"><span class="pre">F4PGA_SHARE_DIR</span></code>), so that
|
|||
|
|
CLI utilities can find tools and assets.</p></li>
|
|||
|
|
<li><p>Downloading and extracting the Architecture Definition tarballs.</p></li>
|
|||
|
|
<li><p>Getting the environment and requirements files, by cloning f4pga-examples or f4pga-arch-defs, or by using the ones
|
|||
|
|
included in the tarballs.</p></li>
|
|||
|

<li><p>Bootstraping the Conda environment and optionally installing additional tools.</p></li>

<p>For every board, the loading process may vary and different tools may be required.
|
|||
|
|
Typically, each tool supports a specific target family or the lines of products of a vendor.
|
|||
|
|
Some of the most known are listed in <a class="reference external" href="https://hdl.github.io/constraints/ProgDebug.html#progdebug" title="(in FPGA Board Constraints vlatest)"><span class="xref std std-ref">hdl/constraints: Programming and debugging</span></a>.
|
|||
|
|
The tools used in the F4PGA Toolchain are e.g. <code class="docutils literal notranslate"><span class="pre">OpenOCD</span></code>, <code class="docutils literal notranslate"><span class="pre">tinyfpgab</span></code> or <code class="docutils literal notranslate"><span class="pre">tinyprog</span></code>.
|
|||
|
|
Moreover, <a class="extlink-gh reference external" href="https://github.com/trabucayre/openFPGALoader">OpenFPGALoader</a> is a universal utility for programming FPGA devices, which is
|
|||
|
|
becoming an alternative to the fragmentation in bitstream loading tools.
|
|||
|
|
OpenFPGALoader supports many different boards with FPGAs based on the architectures including xc7, ECP5, iCE40 and many
|
|||
|
|
more.
|
|||
|
|
It can utilize a variety of the programming adapters based on JTAG, DAP interface, ORBTrace, DFU and FTDI chips.</p>

|
|||
|
|
<p>OpenFPGALoader is available in several packaging solutions.
|
|||
|
|
It can be installed with distribution specific package managers on Arch Linux and Fedora.
|
|||
|
|
There are also prebuilt packages available in <a class="reference external" href="https://anaconda.org/litex-hub/openfpgaloader">conda</a>
|
|||
|
|
or packages in tool <a class="extlink-gh reference external" href="https://github.com/trabucayre/openFPGALoader/releases">repository</a>.
|
|||
|
|
OpenFPGALoader can also be built from sources.
|
|||
|
|
For installation guidelines using both prebuilt packages and building from source, please refer to instructions in
|
|||
|
|
<a class="extlink-gh reference external" href="https://github.com/trabucayre/openFPGALoader/blob/master/INSTALL.md">readme</a>.</p>
