[SOLVED] No matching "SUBCKT"

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.

Regards
Clive

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.

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:

It works, but then 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!
