Boundary’s coordinates

sooky
Hi friends:

I want to know is it possible to get the Boundary’s coordinates of a cell.

How to get this.

Thanks
  • Bernd

     Get the cell view Id
     either for an cell  view open in a window with
    d_cvId = geGetEditCellView( )
     or with
    d_cvId = dbOpenCellViewByType( t_libName t_cellName t_viewName )
    and then
     dbComputeBBoxNoNLP(  d_cvId )
     => l_bBox
    returns the list with the bounding box coordinates.

    Also, d_cvId->bBox will return that cell's bounding box.

    All,

    I'm looking to get the outline of all instances and shapes in a cellview, akin to a shrink wrapped boundary, to create a metal fill keepout halo around the block.

    The only way I can see to do this at the moment is flatten everything, convert all shapes to a common layer, and merge.

    Is there another means of doing this, ie a command that would give the coordinates of the outline?

    Thanks

    First of all, the forum guidelines ask you not to post on the end of old threads. This one is 5 and a half years old!

    There was some discussion in this thread on finding the convex hull of a set of shapes - so a similar problem.

    Regards,

    Andrew.

    Thanks Andrew,

    I was not aware of this, duly noted.

    Brian.
