====== FPGA on FreeBSD ======

Welcome to the [[https://en.wikipedia.org/wiki/Field-programmable_gate_array|FPGA]] on [[https://www.freebsd.org/|FreeBSD]] WIKI! You will find resources, information, hints and references that should be useful to enthusiasts and developers of Field Programmable Gate Array (FPGA) devices.

===== Vendors =====

Below you will find list of FPGA vendors:

  * [[https://www.xilinx.com/|Xilinx]] / [[https://github.com/xilinx|Xilinx at GitHub]]
  * [[https://www.intel.com/content/www/us/en/products/programmable.html|Intel]] (acquired [[https://en.wikipedia.org/wiki/Altera|Altera]]) / [[https://github.com/intel|Intel at GitHub]]
  * [[https://www.microsemi.com/product-directory/1636-fpga-soc|MicroSemi]] / [[https://github.com/MicrochipTech/|MicroChip at GitHub]]
  * [[https://www.latticesemi.com/fpga|Lattice]]

===== Open-Source-Cores =====

List below presents Open-Source-Hardware IP Cores that you can implement on your own FPGA devices:

  * [[https://riscv.org/RISC-V]] is a free and open ISA enabling a new era of processor innovation through open standard collaboration.The RISC-V ISA delivers a new level of free, extensible software and hardware freedom on architecture, paving the way for the next 50 years of computing design and innovation.

===== Open-Source-Hardware =====

  * [[https://www.crowdsupply.com/search?q=fpga|CrowdSupply]] is the hub for Open-Source-Hardware devices.
  * [[https://github.com/im-tomu/tomu-hardware|TOMU]], [[https://github.com/im-tomu/fomu-hardware|FOMU]] and the [[https://www.crowdsupply.com/quicklogic/qomu|QUOMU]] are tiny programmable FPGA devices that fits inside a USB port that is compatible with a fully open source chain and capable of running Python on a RISC-V core or the whole RTOS like [[https://www.zephyrproject.org/|ZEPHYR RTOS]].
  * [[https://tinyfpga.com/|TinyFPGA]] boards are a new series of low-cost, open-source FPGA boards in a tiny form factor. Solder on pins for use in a breadboard or PCB socket; or solder connectors, wires, and components directly onto the board.
  * [[https://github.com/icebreaker-fpga|iCEBreaker]] is the %%OpenSource%% iCE40 FPGA development board designed for teachers and students.
  * [[https://www.crowdsupply.com/qwerty-embedded-design/beaglewire]] is a completely open source FPGA development board. Unlike most other FPGA dev boards, the %%BeagleWire%%’s hardware, software, and FPGA toolchain are completely open source. The %%BeagleWire%% is a Beaglebone compatible cape based on the Lattice iCE40HX FPGA.
  * [[https://wiki.seeedstudio.com/Spartan-Edge-Accelerator-Board/|Spartan Edge Accelerator Board]] is the %%OpenSource%% Xilinx Spartan-7 and ESP32 multimedia development kit.
  * [[https://www.microsemi.com/hifive-unleashed-expansion-board|MicroSemi HiFive Unleashed Expansion Board]] adds PCIe root port capability to the %%HiFive%% Unleashed board, enabling you to create a RISC-V PC. Use it to add HDD’s, SSDs, audio cards, network adapters, and/or graphics cards. You can port your Linux distro to this platform along with all of your favorite packages. Accelerate software development with an out-of-the-box solution.

===== SDK =====

==== Open-Source ====

List below presents Open-Source projects that are not yet ported to %%FreeBSD%% but stands as strong alternative to closed-source vendor utilities:

  * [[https://symbiflow.github.io/|SymbiFlow]] is a fully Open-Source toolchain for the development of FPGAs of multiple vendors. Currently, it targets the Xilinx 7-Series, Lattice iCE40, Lattice ECP5 FPGAs, %%QuickLogic%% EOS S3 and is gradually being expanded to provide a comprehensive end-to-end FPGA synthesis flow.
    * [[https://github.com/SymbiFlow/prjxray|Project X-Ray]] documents the Xilinx 7-Series FPGA architecture to enable development of open-source tools. Our goal is to provide sufficient information to develop a free and open Verilog to bitstream toolchain for these devices.
    * [[https://github.com/SymbiFlow/icestorm|Project ICE Storm]] aims at documenting the bitstream format of Lattice iCE40 FPGAs and providing simple tools for analyzing and creating bitstream files.
    * [[https://github.com/SymbiFlow/prjtrellis|Project Trellis]] enables a fully open-source flow for ECP5 FPGAs using Yosys for Verilog synthesis and nextpnr for place and route. Project Trellis itself provides the device database and tools for bitstream creation.
  * [[https://www.yosyshq.com/open-source-projects|YoSysHQ]] is the new home for the team maintaining Yosys and the related Open Source EDA projects.

==== Closed-Source ====

List below presents closed-source vendor license restricted utilities that may be also used for free in a restricted manner. These utilities are provided for Windows and Linux but does not fully work on %%FreeBSD%% using Linux Compatibility Layer. It may provide useful shell utilities though:

  * [[https://www.xilinx.com/support/download.html|Xilinx Vivado]] is now the unified installer for all known Xilinx devices and uilities (inluding historical ISE). It requires over 50GB+ of disk space as it contains all utilities, compilers, libraries, Python and Java runtime. Installer and Shell utilities run on %%FreeBSD%% but no GUI functionality works. Will not provide native build for %%FreeBSD%%.
  * [[https://www.latticesemi.com/Products/DesignSoftwareAndIP/FPGAandLDS/Radiant|Lattice Radiant]] is a set of tools for Certus-NX, %%CrossLink%%-NX, iCE40 %%UltraPlus%% devices. Installer does not work on %%FreeBSD%%. Will not provide native build for %%FreeBSD%%.
  * [[https://www.latticesemi.com/Products/DesignSoftwareAndIP/FPGAandLDS/iCEcube2|Lattice iCEcube2]] is a set of tools for iCE40 %%UltraPlus%%, iCE40 Ultra/%%UltraLite%%, iCE40 LP/HX/LM devices. Installer and Shell utilities run on %%FreeBSD%% but no GUI functionality works. Will not provide native build for %%FreeBSD%%. This utility is obsoleted by Radiant.
  * [[https://www.latticesemi.com/latticediamond|Lattice Diamond]] is a set of tools for %%CrossLinkPlus%%, %%CrossLink%%, ECP5/ECP5-5G, LatticeECP3, Mach-NX, MachXO3D, MachXO3, MachXO2, LatticeXP2 devices. Installer and Shell utilities run on %%FreeBSD%% but no GUI functionality works. Will not provide native build for %%FreeBSD%%.
