Abstract
Pattern matching using anchors during integrated circuit (IC) verification is disclosed. According to one embodiment, a method includes obtaining match time estimates associated with pattern anchors of different anchor types for an IC pattern, generating revised match time estimates based on a target IC layout, and then selecting the pattern anchor associated with the shortest revised match time estimate. Then, target anchors of the same anchor type as the selected pattern anchor are generated for the target IC layout, and the target IC layout is searched for the IC pattern using the selected pattern anchor and the target anchors.
