newbie's question: how to delete an object using SKILL

llobak

Hi,

 I'm new to SKILL programming and I want to write a program that delete certain layer from certain library. For example, i want to delete all the metal1 object in all the cell in "a" library. Can someone please help me? below is part of my program:

 

procedure( delLayer( libName )
    count = 0
    lib = ddGetObj( libName)
   
        foreach( cell lib~>cells
        if( setof( the_view cell~>views the_view~>name == "layout") then
           
            cv = dbOpenCellViewByType( libName cell~>name "layout")
           
foreach(layer cv~>shapes~>layerName
                if( layer == "MET1" then
                   **** need help in this area ***

I've tried dbDeleteObject() but i just can't seems to get it right
                   
                    count++ );if
                    );foreach layer
                   
                    dbClose( cv)
        );foreach cell
        );if setof
);procedure

  • Hi,

    There are more simple way to grab all the shapes with layer rather than using cv~>shapes. A better propose is using setof(x cv~>lpps x~>layerName == "METAL1"). This will save time and less steps needed instead of running on all shapes in the cell view.

    I did some modication on your code. Please try it. 

    procedure( delLayer( libName )
        count = 0
        lib = ddGetObj( libName)
       
            foreach( cell lib~>cells
                if( setof( the_view cell~>views the_view~>name == "layout") then
               
                cv = dbOpenCellViewByType( libName cell~>name "layout")
               
                foreach( shape car(setof(x cv~>lpps x~>layerName == "MET1"))~>shapes

                   dbDeleteObject(shape)

                    count++ 

                )

                ;;foreach(layer cv~>shapes~>layerName
                ;;    if( layer == "MET1" then
                ;;      **** need help in this area ***

                ;;I've tried dbDeleteObject() but i just can't seems to get it right
                ;;       
                ;;        count++ );if
                ;;        );foreach layer
                       
                        dbClose( cv)
            );foreach cell
            );if setof
    );procedure

     

    BTW, there is a lot of space to improve in your script such as in checking for layout view. You can check whether the cell view is layout or not by checking its cell view type (eg: cv~>cellViewType == "maskLayout")

    Cheers.
