Some embodiments of the invention provide a process for designing and manufacturing an integrated circuit (“IC”). The process selects a wiring configuration and an illumination configuration. The process uses the selected wiring configuration to design an IC layout. The process then uses the selected illumination configuration to manufacture the IC based on the designed IC layout. Some embodiments select a wiring configuration based on the selected illumination configuration. In some embodiments, selecting the illumination configuration entails selecting at least one stepper lens for the IC layout, where the stepper lens illuminates at least one mask for at least one particular layer of the IC layout. Also, in some embodiments, selecting the wiring configuration entails defining the width and/or spacing of the routes along different directions on at least one particular wiring layer of the IC layout.
