[SOLVED] No matching "SUBCKT"

[clive.seguna@gmail.com]

Hi All ,

I am using a tie-down diode TDNDSX. But when running LVS I am obtaining the attached error.

https://obrazki.elektroda.pl/2204379500_1391116594.png

How should I proceed.

Thanks.

How should I proceed.

It looks like the simulator can't find the TDNDSX diode in the libraries of your simulation setup. Check those libs; if necessary add the missing lib!

Maybe you need to re-generate netlist. Please check the netlist file. Maybe you can post your netlist file for further help.

How I can check if I have a missing library ?

Netlist file is being generated and component is present.

Following is a copy of the NETLIST file, where one can see the tdndsx dioide.

Re: No matching "SUBCKT"

How I can check if I have a missing library ?

XC0 vdd! sub! tdndsx area=0.16e-12 perim=1.6e-6

If you can't find the library which contains the tdndsx subcircuit, I'd suggest to try and replace it by a (level=3) standard diode call:

DC0 vdd! sub! D area=0.16e-12 peri=1.6e-6

It works, but then I still don`t obtain a clean LVS or DRC due missing instance tdndsx in schematic .

Re: No matching LVS

... I still don`t obtain a clean LVS or DRC due missing instance tdndsx in schematic .

You have to instance a corresponding (standard) diode in your schematic, of course!

If the DRC reports an error, this is due to a different cause. May be width or spacing violation. Check the error message!
