  • I pulled the following code from Article 20093020 on http://support.cadence.com. It uses all_fanout to report the pins in the path then uses selectPin to select the nets. Hope this helps:

    deselectAll
    all_fanout -from <pin/port name>  -trace_through all > pin_list_file.txt
    set pinfile [open "pin_list_file.txt" r ]
    set file_data [read $pinfile ]
    close $pinfile

    foreach pin  $file_data {
       selectPin $pin
    }
