How to know all the layers present in a PCELL

RFStuff over 11 years ago

Dear ALL,

I want to know all the layers present in a PDK cell.

Is there any way ( by some skill code or command ) to know all the layers present in the CELL

Kind Regards,

Select the instance, make sure it's at full depth (so all hierarchy loaded), and then:
inst=car(geGetSelSet())
foreach(mapcar lpp inst~>master~>lpps list(lpp~>layerName lpp~>purpose))
The second statement will give you a list of the layer purpose pairs (as lists of strings).
Andrew.

In the layout editor hit shift-F or set the display stop level to 32. This will ensure any hierarchy beneath the Pcell is loaded. Alternatively use dbOpenHier(inst~>master 32) (could also use dbOpenHier(geGetEditCellView() 32)
