leLayerSize didn't work for pcell, is there any way around it?

kpai

Hi,

My current pmos pcell came with a fix NW around it, but due to our design need, we need to have an extra large NW from OD outward.

Therefore, I've use leLayerSize as following and hope that it will work.

cv=geGetEditCellView()

leLayerSize(cv list("OD" "drawing") 1.5 list("NW" "drawing"))

But, as the result, leLayerSize command didn't recoganize pmos and return me a nil.

As I tried to change the "display level" to 2 and wonder if leLayerSizer will work.  Still, it didn't work.

But, as I tried to cover the pmos device with OD over to whatever it came with it then set the leLayerSize command again.

This time it works and I saw the extra NW layer over it as I want to.

From this, I realized that leLayerSize didn't work on pcell.   Is there any way around it?

By the way, I'm using 5.10.41 version.

Thanks,

Kathy

  • Kathy,

    I think it would be wise to go on a SKILL course - you've managed to significantly change my suggestion so that it wouldn't work...

    Various things you've done wrong:

    1. inst in your case is a list of instances, rather than a single instance in my case
    2. You are looking for the OD layer purpose pair object in the top level cellView, rather than in the master for the pcell instance
    3. It probably therefore doesn't find any OD shapes.
    4. And hence no NW gets created
    5. Not sure why you changed it the way you did. It suggests you really don't understand what an instance is.

    If you want to process all the instances, you could do:

    cv=geGetEditCellView()
    foreach(inst cv~>instances
      master=inst~>master
      ; find the LPP object within the pcell instance
      OD=car(exists(lpp master~>lpps lpp~>layerName=="OD" && lpp~>purpose=="drawing"))
      ODshapes=foreach(mapcar shape OD~>shapes
        dbCopyFig(shape cv inst~>transform)
      )
      dbLayerSize(cv "NW" ODshapes 1.5)
      ; remove the temporary copy of OD shapes into the cellView
      foreach(shape ODshapes dbDeleteObject(shape))
    ) ; foreach inst
