How to flatten a gds/oas file?

SSR

Hi,

Is it possible to flatten a gds/oas file in command-line before streaming in to the Virtuoso env?

If yes, whats the method? If not, is this something that can be achieved using a SKILL code?

Thanks

  • Hi Ram,

    Here is an example to flatten an instance in SKill :

    pavement=dbOpenCellViewByType( "your_lib" "pavement" "layout" "maskLayout" "r")  cv= geGetWindowCellView()

    inst=(dbCreateInst cv pavement nil 0:0 "R0");<== insert pavement in cellView

    dbFlattenInst(inst 1 nil t)

    Although, it will flatten only one level of depth in the hierarchy. I think there is in one menu a Flatten-all hierarchy button.

    Furthermore, if you want to simplify the gds and reduce data, you can possibly merge shapes and polygons :

    geSelectAllFig() leHiMerge() leHiConvertShapeToPolygon()

    Hope it helps,

    Regards
