Abstract

A process for manufacturing integrated circuit devices includes providing a set of original color rules defining an original color rule space and defining a design space. The improvement involves applying a perturbed color rule space to the router processing engine to expose double pattern routing odd cycle decomposition errors, and reconfiguring the router processing engine in accordance with the exposed decomposition errors.
