How export Calibre layout netlist that contain subckt nodes

[boki]

Dear All:

When I export layout netilst by Mentor Calibre PEX, the netilst file
will convert all nodes as number even power node or input/output node
and take no subckt node for user. Is there any method or setup can I
use for get completed subckt SPICE file.



I have input/output node/pin in my layout, and I can get match on LVS
check. But the layout netlist report is no contain those nodes again.

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


The problem is no input/output/power nodes on layout export netlist?
Could you please tell me how to fix it? or any setup method?

Thanks a lot!
Best regards,
Boki.
