Pin labels in Virtuoso from Encounter OA

nevsan
I'm trying to get a mixed signal environment up and running. I can save the Encounter database to OA using an interoperable PDK (standard cell/routing tech lef in OA referencing base PDK). The layout looks fine in Virtuoso, but one thing that I am missing is pin labels (the kind I need for LVS). The wierd thing is that if I stream the design out from Encounter to GDSII and then stream it in, all of the pin labels are there on the proper layers. They just don't show up in the OA layout (doesn't matter whether I use saveDesign or oaOut).

  • Here's what I settled on for an export script that has pin labels

        setOaxMode -textPurpose label
        set labels {}
        set orientations [dict create R0 R270 R90 R0 R180 R90 R270 R180]
        foreach term [list {*}[dbGet top.terms] {*}[dbGet top.pgTerms]] {
            lappend labels [add_text -label {*}[dbGet $term.name] -height 0.5 -alignment centerLeft \
                                -pt [dbGet $term.pt] -layer [dbGet $term.layer.name] \
                                -orient [dict get $orientations [dbGet $term.orient]]]
        }

        # Stream into OA

        oaOut lib cell view -autoRemaster 

        # Remove labels

        foreach label $labels {dbDeleteObj $label}
