The apparatus determines features within a circuit layout, distance constraints for at least one of the features, group constraints for the features based on the distance constraints, the group constraints defining limits on groups assignable to each of the features. In addition, the apparatus receives an integrated circuit layout including a plurality of abutting cells. The apparatus then determines whether group constraints of a second cell conflict with group constraints of a first cell, the second cell abutting with the first cell, and configures a subset of the group constraints of the second cell based on the group constraints of the first cell and based on the group constraints of the second cell that conflict with the group constraints of the first cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Systems and methods for group constraints in an integrated circuit layout","description":"Methods and apparatuses for configuring group constraints of features of cells for a multi-patterning process are provided.
