Nexus support is currently experimental, and has only been tested with engineering sample silicon.
### nextpnr-gowin
For Gowin support, install [Project Apicula](https://github.com/YosysHQ/apicula). If a virtualenv is used, the path to `gowin_bba` needs to be provided as follows:
```
cmake . -DARCH=gowin -DGOWIN_BBA_EXECUTABLE=path
make -j$(nproc)
sudo make install
```
- Examples of the Gowin flow for a range of boards can be found in the [Project Apicula Examples](https://github.com/YosysHQ/apicula/tree/master/examples).
