    Abstract: Systematic fault localization systems and methods are provided which utilize computational GDS-assisted navigation to accelerate physical fault analysis to identify systematic fault locations and patterns. In some embodiments, a method includes detecting a plurality of electrical fault regions of a plurality of dies of a semiconductor wafer. Decomposed Graphic Database System (GDS) cross-layer clips are generated which are associated with the plurality of electrical fault regions. A plurality of cross-layer common patterns is identified based on the decomposed GDS cross-layer clips. Normalized differentials may be determined for each of the cross-layer common patterns, and locations of hotspots in each of the dies may be identified based on the determined normalized differentials.
