| **This repository is focused on the development of architecture support in F4PGA. Start with the [](https://f4pga-examples.readthedocs.io) if you are looking to use the |
| tools.** |
| |
| This repo contains documentation of various FPGA architectures, it is currently concentrating on: |
| |
| * Lattice |
| * [iCE40](lattice/ice40) |
| * [ECP5](lattice/ecp5) |
| * AMD/Xilinx |
| * [Series 7](xilinx/xc7) (Artix, Kintex and Zynq) |
| * [QuickLogic](quicklogic) |
| |
| It includes: |
| |
| * Black box part definitions |
| * Verilog To Routing architecture definitions |
| * Documentation for humans |
| * Verilog simulations |
| |
| The aim is to gather useful documentation (both human and machine readable) about the primitives and routing |
| infrastructure for these architectures. |
| We hope this enables growth in the open source FPGA tools space. |
