Abstract
Aspects of the invention relate to pattern matching of layout design data. Layout design data is searched to identify configurations of geometric elements that match a reference pattern based on an anchor edge in the reference pattern. An edge in a search window area matching the anchor edge may first be selected as anchor matching edge. A search portion of the reference pattern is then compared with the region of the search window area corresponding to the selected anchor matching edge.
