    Hi, Dear all,

    I have some instance in my design, and I want to get the location of
    each instance's pin. Is there any function can do such thing or I need
    to transform the pin's bBox? Thanks in advance.

    You would need to use dbTransformBBox() to transform the coordinates. You might
    also need dbConcatTransform() to transform throughout the hierarchy.

    You can find some examples of these functions by doing a google search on
    the comp.cad.cadence group.

    Regards,

    Andrew.

    Hi,
    you can get the location of an instance's pin by using this code:

    IO= dbOpenCellViewByType(bib cel view "maskLayout" "r")
    Inst=dbCreateInst(testchip IO "" '(0 0) "0" 1)
    pin_list=Inst~>pins~>fig~>bBox
