changing LSW valid layers to ones only in layout

JoeV

The problem statement is that I want to change my LSW on the fly to show me only the layers that are present in my layout and hide all the rest. It seems like the breakdown in steps is

determine a list of layers in the layout

set the valid layers in LSW to the list

re display the LSW

However, I cannot find the skill functions that would do these things. Please help!

  • Hi JoeV

     I would suggest posting this question to the Skill or Custom IC design forums.

    To get things started you can query the layout cellview to determine the layers in use as follows:

     From the CIW enter the following skill commands:

    cvId = geGetWindowCellView()  ;;;<--- returns the DB ID of the current cellview.

    lpps = cvId~>lpps ;;;<--- get a list of Layer-Purpose Pairs

    lpps~>layerName ;;; <--- prints a list of layer names

    lpps~>purpose ;;; <--- prints a list of layer purposes

     You next have to determine how to use this information to manipulate the list of valid layers displayed in the LSW.

     Let us know how it goes...this appears to be a useful feature.
