Enhanced model-based hinting fixes multi-layer lithographic hotspots
Enhanced model-based hinting improves litho hotspot repair in advanced node designs
New algorithms that can consider DRC between different layers, enclosure rules between metals and vias or contacts, and complex MP spacing constraints enable more accurate analysis, while adding more flexibility to generated hints by enabling the engine to suggest moving complete metal polygons (including any enclosed via), not just a group of edges. Adopting an enhanced MBH flow can help design companies deliver advanced node designs on schedule while ensuring they comply with all design rules and MP constraints, and deliver the intended performance.
