@Tim Edwards Another issue that you might already be aware of, but I got LEF extraction "hanging" (seemingly never finishing, left it for hours ...) on some GDS ?

No, I don't think I've seen that one. Can you post a reproducible example?

Ack will do. I'll open an issue (although probably on on monday, with the chipignite tapeout, I'm busy with other things 😅 )

I won't be able to look at it until at least Tuesday, so that works for me. : )
