add an ivCellType property (value: graphic) in all the layout cellviews of a library

isazulkc
Hi, I want to add an ivCellType: graphic to all my layout cellview. I know I can do it individually in each cellview, but it's too long. There is an efficient way to do it at a library level ? Thanks

  • Hi isazulkc

    You can use the following skillscript. It will add "ivCellType" property with value "graphic" to all cells in a library. Please save it as "createprop.il" in the working directory and load it in ciw using:

    load "createprop.il"

    Execute it using:

    CCScreateProp("yourLibName")
    OR
    CCScreateProp("yourLibName" "ivCellType" "string" "macro")

    Diva does not check for ivCellType property at the library level.

    Best regards

    procedure( CCScreateProp(myLib @optional (myProp "ivCellType")
        (propType "string") (value "graphic"))
       let( (libID bag)
          libID=ddGetObj(myLib)
          foreach( cell libID~>cells
              bag=dbOpenBag(cell "a")
              unless( dbFindProp(bag myProp)
                dbCreateProp(bag myProp propType value)
            printf("Property added for cell %s\n" cell~>name)
              ) ;unless
              dbSaveBag(bag)
              dbCloseBag(bag "a")
          ) ;foreach
       ) ;let
    ) ;procedure

    createprop.il

  • Hi isazulkc

    It is not possible to add a library level "ivCellType" property. You can use the following skillscript to add "ivCellType=graphic" to all cells in a library. Please enter the following in ciw after loading the script:

    CCScreateProp("yourLibName")

    Best regards
    Quek

    procedure( CCScreateProp(myLib @optional (myProp "ivCellType")
            (propType "string") (value "graphic"))
       let( (libID bag)
          libID=ddGetObj(myLib)
          foreach( cell libID~>cells
              bag=dbOpenBag(cell "a")
              unless( dbFindProp(bag myProp)
                dbCreateProp(bag myProp propType value)
                printf("Property added for cell %s\n" cell~>name)
              ) ;unless
              dbSaveBag(bag)
              dbCloseBag(bag "a")
          ) ;foreach
       ) ;let
    ) ;procedure   

    createprop.il
  • Hi Quek, Thanks for the script, I just try it. It add the "ivCellType" property to the cell property, but for macrocell extraction I need to add this property to the layout cellviews properties. How can I modify this script to add ivCellType graphic in the Layout Cellview properties instead of the cell property. Thanks a lot! Isazulkc

  • Hi isazulkc

    You can try this:

    procedure( CCScreateProp(myLib @optional (myProp "ivCellType")
            (propType "string") (value "graphic"))
       let( (libID bag)
          libID=ddGetObj(myLib)
          foreach( cell libID~>cells
              bag=dbOpenBag(cell "a")
              unless( dbFindProp(bag myProp)
                dbCreateProp(bag myProp propType value)
                printf("Property added for cell %s\n" cell~>name)
              ) ;unless
              dbSaveBag(bag)
              dbCloseBag(bag "a")
              cv=dbOpenCellViewByType(myLib cell~>name "layout" "" "a")
              evalstring(strcat("cv~>" myProp "=\"" value "\""))
              dbSave(cv)
              dbClose(cv)
         ) ;foreach
       ) ;let
    ) ;procedure

  • Hi Quek, There is some error when running as all the cell in the library don't have a layout view. I'm sure only a condition line in the script will solve the problem. However I don't have any knowledge in skill. Do you have some good reference to learn skill or do I need only to go through cadence reference and user guide? Thanks to tell me the condition line to add and some goods reference for skill. Best regards, Isazulkc

  • Isazulkc,

    Change this bit:

              evalstring(strcat("cv~>" myProp "=\"" value "\""))
              dbSave(cv)
              dbClose(cv)

    to:

              when(cv
                dbSet(cv value myProp)
                dbSave(cv)
                dbClose(cv)
              )

    I also changed the evalstring bit to use dbSet which is cleaner than using run-time evaluation.

    Note that I didn't test any of this - it was just from visual inspection of the SKILL code.

    Regards

    Andrew.

  • Hi Andrew,

    Thanks, that works fine now :-). Could you advise some good references to get into and develop skill script.

    Best regards,
