Abstract

Systems and methods for generating coloring constraints for layout design data. A method includes receiving or determining a constraint rule, by a computer system, for a constraint between geometric elements in the layout design data. The method includes generating constraints according to the one or more constraint rules. The method includes creating one or more groups according to the generated constraints. The method includes storing the generated constraints and the one or more groups in a design layout database. Also systems and methods for identifying elements in a design layout having multiple levels of hierarchical cells.
