copy hierarchical layer to top level

SonnyTang

Hi Sir:

    I need to copy one particular layer in instance to top level. For example, the "PAD" layer was drawn in the IO cells and instanced on the top level. I need to duplicate this "PAD" layer on the top level. Can any one help for the Cadence Skill code to do that?

  • Dear Andrew:

           Thanks for your reply. In fact, I am using ICFB 5.10.41_USR5.90.69 and I can not find "getOpenCellView" can I use "geGetWindowCellView" in stead for CCSflattenAndMerge? In fact, after I change it as follows, it runs well but I did not find the PAD layer move to top level. Did I do something wrong? I am sorry, I am new for the skill code, I may ask something silly. Thanks

    src=geGetWindowCellView()

    dst=dbOpenCellViewByType(src~>libName src~>cellName "flattened" "maskLayout" "w")

    CCSflattenAndMerge(src dst '("PAD" "drawing"))

    Regards,

    Sonny

  • Sonny,

    My apologies - there's a typo in the comments in my code. It should say src=geGetEditCellView() (or geGetWindowCellView would do unless you're using edit in place). Note that the code will copy the shapes into another cellView - so you should find that you have a view called "flattened" that got created with the PAD shapes in. You could copy these into your source cellView. Or I think you should be safe just using CCSflattenAndMerge(src src '("PAD" "drawing")) (without opening dst). You might want to check that the shapes ended up in the flattened view first before trying it outputting directly into your source cellView (I've not tested that myself).

    Regards,

    Andrew.
