This repository contains the platforms/targets currently supported by LiteX:
- The platform provides the defintion of the board:IOs, constraints, clocks, components + method to load and flash the bitstream to it.
- 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](https://github.com/litex-hub/linux-on-litex-vexriscv) project that is just using a specific configuration (Linux-capable CPU, additional peripherals). Basing your design on provided targets allow to to reduce code duplication between very various projects.

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:
