Skill code to delete duplicate pin

Duc Loc

Hi all,

In my layout, I have a lot of duplicate pins. I want to delete all the duplicate pins and keep the highest metal pin.

Do anyone have the skill code to do that, or know a way to do that ?

Thanks in advance,

Duc Loc

  • Hi Duc Loc,

    This is quite simple, here is an example:

    ;; Browse all nets
(foreach net (geGetEditCellView)->nets
  ;; Delete pins on the same net
  ;; Pins are sorted by layerNum and first one is skipped 
  (foreach pin_fig (cdr (sort net->pins~>fig
                              (lambda (fig0 fig1)
                                (greaterp fig0->layerNum fig1->layerNum)
                                )))
    (dbDeleteObject pin_fig)
    ))

    Please note that I sort the pins by layerNum to find the higher metal (this should work fine for metals with most DKs)

    With my code I have no idea of which pin is deleted in case duplicated pins have the same layer and no warning will be printed as well

    Cheers,
    Aurélien
