How to get the object id of deleted instance, net, wire or anything?

Hi Purbayan,

Your issue is not really clear...

Are you talking about a native GUI or a custom one?

If it is a native one, you won't be able to do anything except if there is a public trigger you can edit to update your report field

If it is a custom one (and you can edit it), you will have to update it's callback to update your field

Otherwise this is not optimal but you can check the values of your field and remove the elements not present in the schematic

The harder part is to define when you update your field...

Otherwise if the GUI you are referring to is the schematic editor, you can rebind the "delete" key to a custom function that will do the deletion and update your report field accordingly

Hope this helps

Cheers

Hi Aurélien,

Actually what i want is if a user deletes an object from schematic with usual delete key i just want to get the object id of that specific object and delete that entry from the list also. I want to trigger it when user clicks delete(the usual delete function provided by cadence donot prove any feedback on what  object id got deleted).

The second Method that you suggested is check the schematic, the problem with this is if a schematic have more than 10000 objects then checking updating will be very slow with foreach loop. If there is any faster way available to do that i would really appreciate it.

Also thank you for the valuable suggestions.

Actually it depends on what you want to do precisely

If you have to browse the hierarchy, your script might take more time to run.

You also might want to avoid prints that will be time consuming and quite useless with such a number of objects

If you don't need to parse the instances, you might want to use instances headers instead to reduce the number of processed items

You should also avoid returning the list of >10000 objects in your code and might consider using generators instead

;; This is to avoid as it keeps all the instances at the same time in memory
insts=(geGetEditCellView)->instances
foreach inst insts ...

;; This should be a little better:
;;
;; Browse instances headers
(let ((inst_header_gen (dbStartGenInstHeader (geGetEditCellView)))
      inst_header)
  (while (setq inst_header inst_header_gen->next)
    ;; Browse instances
    (let ((inst_gen (dbStartGenInstHeaderToAnyInst inst_header))
          inst)
      (while (setq inst inst_gen->next)
        ;; Put your body here
        ...
        ));insts
    ));inst_headers

That is really great insight.

Thank you Aurélien for the code.
