    [> Intro

    From the very tiny Fomu to large PCIe accelerator boards....

    This repository contains the platforms/targets currently supported by LiteX:

    • The platform provides the definition of the board: IOs, constraints, clocks, components + methods to load and flash the bitstream to it.
    • The target provides a LiteX base design for the board that allows you to create a SoC (with or without a CPU) and integrate easily all the base components of your board: Ethernet, DRAM, PCIe, SPIFlash, SDCard, Leds, GPIOs, etc...

    The targets can be used as a base to build more complex or custom SoCs. They are are for example directly reused by the Linux-on-LiteX-VexRiscv project that is just using a specific configuration (Linux-capable CPU, additional peripherals). Basing your design on provided targets allows to to reduce code duplication between very various projects.

    First make sure to install LiteX correctly by following the installation guide and have a look at the LiteX's wiki for tutorials, examples of projects and more information to use/build FPGA designs with it.

    Each target provides a default configuration with a CPU, ROM, SRAM, UART, DRAM (if available), Ethernet (if available), etc... that can be simply built and loaded to the FPGA with:

    $ ./target.py --build --load

    You can then open a terminal on the main UART of the board and interact with the LiteX BIOS:

    But this is just the starting point to create your own hardware! You can then:

    • Change the CPU: add --cpu-type=lm32, microwatt, serv, rocket, etc...
    • Change the Bus standard: add --bus-standard=wishbone, axi-lite
    • Enable components: add --with-ethernet --with-etherbone --with-sdcard etc...
    • Load application code to the CPU over UART/Ethernet/SDCard, etc...
    • Create a bridge with your computer to easily access the main bus of your SoC.
    • Add a Logic Analyzer to your SoC to easily observe/debug your design.
    • Simulate your SoC and interact with it at decent speed with LiteX Sim/Verilator.
    • Integrate external cores/CPU to create your own design.
    • etc...

    Please use ./target.py --help to see the pre-built various possibilities.

    Hoping you will find this useful and enjoy it, please contribute back if you make improvements that could be useful to others or find issues!

    A question or want to get in touch? Our IRC channel is #litex at freenode.net

    Note: All boards with >= 32MB of memory and enough logic can be considered as Linux Capable.

    [> Open-hardware boards

    Fully open-hardware boards, the ECP5 and iCE40 ones are even usable with the open-source FPGA toolchains!
