Abstract
In some embodiments, portions of a pattern, generated in a layout process, of a layer in an integrated circuit, such as those of a layer of metallic power lines in a power grid (PG), are removed after the layout process through a computer-implemented process analogous to solving the N-coloring problem. Through this post-processing removal process, pattern portions can be removed so as reduce the coverage of the layer in the fabricated integrated circuit to a desired extent without producing certain harmful effects, such as severing a powerline.
