nextpnr -- a portable FPGA place and route tool =============================================== Supported Architectures ----------------------- - iCE40 Prequisites ----------- - CMake 3.3 or later - Modern C++11 compiler, clang recommended - 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` Building -------- - 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 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 Running -------- - To run the CLI binary, just run `./nextpnr-ice40` - The Python module is called `nextpnrpy_ice40.so`. To test it, run `PYTHONPATH=. python3 python/python_test.py`
