Changing bBox of cell using dbTransformBBox/geTransformUserBBox

egolowen

Hi,

I am trying to reduce the bBox of my cell (it has been enlarged and is much larger than my prBoundary) and I have tried the following commands:

cv_layout = dbOpenCellViewByType("lib" "cell" "layout_test" "maskLayout" "a")
transform = list(list(-10000 -10000) "R0" 1)
dbTransformBBox(cv_layout~>bBox transform)

When I go back and check cv_layout~>bBox, nothing has changed. Am I missing a step? Or is there a different way to change the bBox of an entire cell?

Thanks,
Elizabeth

    Take a look at this post:

    For 6.1.x designs, I had to add the following two commands (to the function in the referenced post) to further help with errant bBoxes:

            mapcar('dbDeleteObject cv~>steiners)
            ;Delete markers that have isVisible set to nil (OA)
            mapcar('dbDeleteObject setof(x cv~>markers !x~>isVisible))
