    SoC Encounter DB Access - Power/Ground Nets Reply
    Hello everybody I am using SoC Encounter 7.1 and I use DB Access methods for layout extraction. Whereas I am extracting the wire information about the wires of the signal nets, there is a problem with the power nets of the design. In perspective, whenever I try to extract wire information about the specific nets, even after doing detailed RC extraction including special nets, there are no wires reported. The 'Verify Connectivity' tool shows no problem with the connectivity of power rings, stripes and followpins. Is there anything I can do with this issue ?I would be grateful if somebody could help me. Thank you very much in advance

     there is a simple script which maybe help you.

    dbForEachFPlanStrip [dbHeadFPlan] stripPtr {

           set name [dbStripName $stripPtr]

            if { $name == "VDD" } {

                   dbForEachStripBox $stripPtr stripBoxPtr {

                           set netPtr [dbStripBoxNet $stripBoxPtr]

                           set netName [dbNetName $netPtr]

                           set shape [dbStripBoxShape $stripBoxPtr]

                              ...............

                     }

                }

    }

    Thank you very much for the immediate response!However, I have run several similar codes using dbStriBoxNet and dbInfoStripBox but still I cannot see wires as in the classic signal nets. Anyway, I would like to thank you again for your help! Kind Regards
