Abstract
Disclosed is an approach for performing pattern classification for electronic designs. One advantage of this approach is that it can use fast pattern matching techniques to classify both patterns and markers based on geometric similarity. In this way, the large number of markers and hotspots that typically are identified within an electronic design can be subsumed and compressed into a much smaller set of pattern families. This significantly reduced the number of patterns that must be individually analyzed, which considerably reduces the quantity of system resources and time needed to analyze and verify a circuit design.
