I still use IC5141-usr6. A third-party design house just sent me a design with OA database. I guess I can use oa2cdb utility to convert this design to IC5141-usr6 database. However, I even cannot find oa2cdb utilitiy. In my ---/IC5141-usr6/tools/bin, I only find oa2pcdb, but no oa2cdb. Any guideline how to convert this OA database to CDB database?
