This repository is focused on the development of architecture support in F4PGA. Start with the  if you are looking to use the
tools.
This repo contains documentation of various FPGA architectures, it is currently concentrating on:
- Lattice
 - AMD/Xilinx
- Series 7 (Artix, Kintex and Zynq)
 
 - 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.
