Abstract: Embodiments according to the present disclosure relate to physically implementing an integrated circuit design while conforming to the requirements of complex color based track systems. In embodiments, the color based track systems can include irregularly spaced and non-uniform width colored tracks. These and other embodiments include a methodology to automatically generate a track pattern for an integrated circuit design that satisfies both design constraints and user inputs. Various alternatives for identifying starting points in the design for automatically generating track patterns are possible.
