Abstract
A computer-implemented method for validating a design is disclosed. The method includes receiving, with the computer, the design, where the design is printable using a multiple-patterning process when the computer is invoked, and where the design includes a plurality of shapes and at least one conflict preventing decomposition of the design into a plurality of multiple-patterning masks. The method also includes forming a subset of the shapes, the subset including the shapes associated with the at least one conflict, categorizing each of the shapes of the subset into one of a plurality of topology types generating one or more stitch candidate solutions for each of the plurality of topology types, and decomposing the design into a plurality of masks.
