nextpnr -- a portable FPGA place and route tool
===============================================

nextpnr aims to be a vendor neutral, timing driven, FOSS FPGA place and route
tool.

Currently nextpnr supports:
 * Lattice iCE40 devices supported by [Project IceStorm](http://www.clifford.at/icestorm/)
 * Lattice ECP5 devices supported by [Project Trellis](https://github.com/SymbiFlow/prjtrellis)
 * *(experimental)* a "generic" back-end for user-defined architectures

There is some work in progress towards [support for Xilinx devices](https://github.com/daveshah1/nextpnr-xilinx/) but it is not upstream and not intended for end users at the present time. We hope to see more FPGA families supported in the future. We would love your help in developing this awesome new project!

A brief (academic) paper describing the Yosys+nextpnr flow can be found
on [arXiv](https://arxiv.org/abs/1903.10407).

Here is a screenshot of nextpnr for iCE40. Build instructions and
[getting started notes](#getting-started) can be found below.

Prerequisites
-------------

The following packages need to be installed for building nextpnr, independent
of the selected architecture:

- CMake 3.3 or later
- Modern C++11 compiler (`clang-format` required for development)
- Qt5 or later (`qt5-default` for Ubuntu 16.04)
- Python 3.5 or later, including development libraries (`python3-dev` for Ubuntu)
  - on Windows make sure to install same version as supported by [vcpkg](https://github.com/Microsoft/vcpkg/blob/master/ports/python3/CONTROL)
- Boost libraries (`libboost-dev libboost-filesystem-dev libboost-thread-dev libboost-program-options-dev libboost-python-dev libboost-dev` or `libboost-all-dev` for Ubuntu)
- Eigen3 (`libeigen3-dev` for Ubuntu) is required to build the analytic placer
- Latest git Yosys is required to synthesise the demo design
