@User Oh, I actually have an update for it that forces diode on lines coming from external pads (because chances that they will be long ...).

cool, will try when it's available. trying to avoid hand patching things if I can

I don't think it's going to fix anything for you, it's more a safety because the flow doesn't seem to detect antenna formed at the

user_project_wrapper

level ... (the LEF for the internal macro lacks all ANTENNA specs). So as a safety I put diodes on all inputs.
