    Dear All:

    When I export layout netilst by Mentor Calibre PEX, the netilst file
    will convert all nodes as simple number even is power node or
    input/output node and convert a not completed subckt node for user.

    My situation:
    I have input/output node/pin in my layout, and I can get match on LVS
    check. But the layout netlist report didn't contain those input/output
    nodes again, just export them as simple number.

    For example:

    Schematic netlist:

    ..SUBCKT BOKI INPUT OUTPUT
    M1 OUTPUT INPUT VSS VSS NCH W=1u L=1u
    M2 OUTPUT INPUT VDD VDD PCH W=1u L=1u
    ..ends

    Layout export netlist: (I have input/output pin there, and LVS match)
    ..SUBCKT BOKI
    M1 1 2 3 3 NCH W=1u L=1u
    M2 1 2 4 4 PCH W=1u L=1u
    ..ends

    The problem is no input/output/power nodes on layout export netlist,
    and there is not a completed subckt for user.

    Could you please tell me how to fix it? or any setup method?

    Thanks a lot!
    Best regards,
    Boki.
