Description
To reproduce locally:
```
make env
make enter
cd proj/hps_accel
make bitstream
```
Symptom is an error from `nextpnr-nexus`:
```
ERROR: Cell type 'CCU2' instantiated as 'tx_phase_FD1P3IX_Q_8_D_LUT4_Z_D_CCU2_S1_S0_CCU2_S1_CIN_CCU2_COUT' is not supported by this device.
```
Our device is `LIFCL-17-8UWG72C`.
It could be that our Litex is too far out of date. In an updated pure Litex installation, I can build the litex-boards target for the EVN board:
```
./lattice_crosslink_nx_evn.py --build --toolchain=oxide
```
This netlist does contain CCU2 cells. Its device is LIFCL-40-9BG400C.
