Thanks, this is unfortunately a bit of a long-running issue in nextpnr, new causes seem to keep popping up. A testcase would be appreciated (although, it's worth noting that small changes will usually tip the balance to or from not routing).
Seems to happen when using amaranth as well. Can you point me in the right direction if I were to look into nextpnr to fix this? I am curious to not only resolve this, but to have a better understanding of the tools.
It seems to never end:
I can provide a reproducible example momentarilly...
