Editing of layout designs for fixing DRC violations

Abstract:

The present embodiments relate to providing an overlap view of external and internal components of all instance circuit cells related to a master circuit cell in a same layout view. A layout of a circuit having a plurality of instance circuit cells of a master circuit cell is provided. Further, a graphical user interface including a user selectable option for an overlay view is provided. In addition, responsive to the selection of the overlay view, the plurality of instance circuit cells of the master circuit cell is determined. In addition, a plurality of sets of circuit elements, each set of circuit elements including external circuit elements that overlap with a corresponding instance circuit cell of the plurality of instance circuit cells is determined. Further, the plurality of sets of circuit elements overlaid on the master circuit cell is displayed on the layout view.
