Similar to the issue #722 I am seeing that synthesis is failing

Thanks for the report @navan93 ! I haven't been able to reproduce it yet because I hit a different issue trying to do a fresh Symbiflow installation.
In case it matters, what OS are you using?
navan93 commented
I am using Ubuntu 22.04 desktop.

This may be related to chipsalliance/yosys-f4pga-plugins#542. In any case, I find that pinning Yosys to an older version resolves the issue: #809.

I hit the same issue when targeting Nexus FPGAs since that flow also uses the yosys-f4pga-plugins:
ERROR: Can't load module `./dsp-ff': /home/tim/CFU-Playground/env/conda/envs/cfu-common/bin/../share/yosys/plugins/dsp-ff.so: undefined symbol: _ZN5Yosys7stringfB5cxx11EPKcz
I'll update the PR to pin Yosys in the place used for that flow.
