Export layout netilst by Mentor Calibre PEX

[boki]

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.
