Abstract

Methods and systems of routing a design layout include setting an inner region and an outer region for modification of structures in an original design layout, in accordance with a minimum spacing that is based on a fabrication process. Routing of trim positions and conductive wire extents is performed within the inner region, based on positions of shapes within the outer region, including node folding of a new constraint graph to minimize perturbations from a previous constraint graph, to generate an updated design layout that can be manufactured using the fabrication process.
