Current view of Cellview

Ivangabs

Hello!

Is there a SKILL code that can check what objects are currently seen in the cellview window? Also a SKILL code to get the coordinates of an object relative to the window? (Both schematic and layout view answers are greatly appreciated)

I would like this SKILL code since I would like to check if the tool successfully "zoomed-in", meaning I will compare the objects that were seen before and after the zooming-in, and check if the object is still centered inside the window.

Thank you for your time!

  • You can find the coordinates that the window is showing by using hiGetViewBBox(windowId). Your need to find the objects shown within the box is a little unusual, but you could use:

    cvId=geGetEditCellView(windowId)
    objects=dbGetOverlaps(cvId hiGetViewBBox(windowId)) ; just top-level objects

    If you have a specific object you want to check relative to the window, I guess you could do:

    objCoord=centerBox(objId~>bBox)
    viewBBox=hiGetViewBBox(hiGetCurrentWindow())
    objRelativeCoord=xCoord(objCoord)-xCoord(lowerLeft(viewBBox)):yCoord(objCoord)-yCoord(lowerLeft(viewBBox))

    the last statement could be more concisely expressed as:

    objRelativeCoord=mapcar('difference objCoord lowerLeft(viewBBox))

    It does seem a bit overkill to me to determine if something successfully zoomed in or not - and simply checking the result of hiGetViewBBox() would seem sufficient to me rather than having to check all the objects within the window.
