nextpnr -- a portable FPGA place and route tool

Supported Architectures

CMake 3.3 or later
Modern C++11 compiler, clang recommended (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)
Boost libraries (libboost-dev or libboost-all-dev for Ubuntu)
Icestorm, with chipdbs installed in /usr/local/share/icebox
Latest git Yosys is required to synthesise the demo design

Use CMake to generate the Makefiles (only needs to be done when CMakeLists.txt changes)
- For a debug build, run cmake -DCMAKE_BUILD_TYPE=Debug .
- For a debug build with HX1K support only, run cmake -DCMAKE_BUILD_TYPE=Debug -DICE40_HX1K_ONLY=1 .
- For a release build, run cmake .
Use Make to run the build itself
- For all targets, just run make
- For just the iCE40 CLI binary, run make nextpnr-ice40
- For just the iCE40 Python module, run make nextpnrpy_ice40
- Using too many parallel jobs may lead to out-of-memory issues due to the significant memory needed to build the chipdbs

To run the CLI binary, just run ./nextpnr-ice40 (you should see command line help)
To start the UI, run ./nextpnr-ice40 --gui
The Python module is called nextpnrpy_ice40.so. To test it, run PYTHONPATH=. python3 python/python_mod_test.py

All code is formatted using clang-format according to the style rules in .clang-format (LLVM based with increased indent widths and brace wraps after classes).
To automatically format all source code, run make clangformat.
