Abstract
An improved approach is described to implement trim data representation for an electronic design. Instead of maintaining a gap shape object for every gap in the layout, existing objects adjacent to the gap location are configured to include attributes of the gap shape. The properties of the gap shape can then be derived from the adjacent objects.
