SKILL function not available

DLev

I am new to SKILL, and am trying to learn how to take smaller layouts and integrate them together into a larger design using a SKILL script.

What I would like to do is read in a layout of a component and extract its dimensions so I can dynamically figure out how to arrange it.

My understanding is that a BBox contains that information using the dbTop, dbBottom, dbLeft, and dbRight functions.

So I tried to open a layout using component_layout = dbOpenCellViewByType(library_name component_name "layout"), which worked fine.

Then I tried using the function component_bbox = dbGetCellViewBBox(component_layout) which is listed in the Documentation Browser, but was given the message "*Error* Eval -  undefined function - dbGetCellViewBBox"

Is there something I need to do to make this function available? Alternately, is there an easier way to get the information I am trying to find?

  • Hi there,

    Actually dbOpenCellViewByType() seems to not be SKILL procedure. 

    I've found it in "Cadence Integrator's Toolkit Database Reference" (C level database access).

    If you want to access the BBox of any component/shape in skill, you can access it like this: component_layout->bBox .

    Best Regards,

    Marcel

  • Hi,

    You can use the bBox attribute on the cell view object that comes back from dbOpenCellViewByType():
    component_layout = dbOpenCellViewByType(library_name component_name "layout")
    component_bbox = component_layout->bBox
    In fact dbGetCellViewBBox() is a C function that is not implemented in SKILL.
