Abstract
In accordance with the present method and system for anisotropic integrated circuit layout we extract a set of anisotropic design rules for integrated circuit manufacturing systems that have directional preference. We enhance various physical design tools to read and process anisotropic design rules in order to generate anisotropic design layout that takes advantage of an anisotropic manufacturing system.
