Hi, Since a year ago, Presto was improved. In release 24.1 S003, Cadence has added two of the missing features stated in my message: -topology extract in the constraint manager -impedance workflow in the view -> panels -> Analysis Workflow But the "derive connectivity" feature is not there yet. However you should not need to use that feature when just doing a simple sync from schematic to PCB. Perhaps, something "not normal" is breaking the connectivity (change in symbol pins#, change in footprint pin # or change in connectivity). Hopefully tech support can help you.
