F4PGA aims to push FPGAs towards more widespread adoption by
optimising and automating FPGA development workflows with a set of
pluggable open source tools.

<span class="underline">How it works</span>
</h2>
<p class="diagrams__paragraph_intro">
To understand how F4PGA works, it is best to start with an overview of <br />
the general EDA tooling ecosystem and then proceed to see what <br />
the F4PGA project consists of.
</p>
<div class="diagrams__diagram" id="eda-ecosystem">
<h3 class="diagram__header">
EDA Tooling Ecosystem
</h3>
<div class="diagrams__content">
<div class="diagrams__paragraph">
<p>
For both ASIC- and FPGA-oriented EDA tooling,
there are three major areas:
</p>
<ul>
<li> hardware description </li>
<li> frontend </li>
<li> backend </li>
</ul>
</div>
<p class="diagrams__paragraph">
While there are a number of open hardware description languages, such as
Verilog, VHDL, Chisel, Migen and Amaranth HDL, the frontend and backend
tooling has been lacking established standard, vendor-neutral solutions.
F4PGA focuses on filling this gap.

F4PGA project structure
</h3>
<div class="diagrams__content">
<p class="diagrams__paragraph">
To become a complete FOSS FPGA toolchain, F4PGA needs a number of
tools and projects to be in place to provide an end-to-end flow.
Thus, F4PGA serves as an umbrella framework for several activities,
the central of which focuses on the creation of FPGA
F4PGA Architecture Definitions, i.e. documentation of how specific
FPGAs work internally.
</p>
<p class="diagrams__paragraph">
Those definitions and serve as input to backend tools like nextpnr and
Verilog to Routing, and frontend tools like Yosys. They are created
within separate collaborating projects targeting different FPGAs -
<a href="https://github.com/F4PGA/prjxray">Project X-Ray</a> for Xilinx 7-Series,
<a href="https://github.com/F4PGA/icestorm">Project IceStorm</a> for Lattice iCE40 and
<a href="https://github.com/F4PGA/prjtrellis">Project Trellis</a> for Lattice ECP5 FPGAs.
