Hello,
I was wondering if you ever found a solution to your problem. I'm new to OA and Encounter and I have the same errors when I save my design to an OA library. It looks like everything is correct, conf file, cds.lib. etc but the error reads:
**ERROR: (ENCOAX-618): Custom via definition for via 'VIAS23' can not be created in OA, because the technology database is readonly. Connectivity will be broken in the saved OA database for these missing vias.
Thanks,
Donna
