Abstract
A route technique includes: receiving an input specifying a plurality of semiconductor device components and their logical connections; determining route information pertaining to a plurality of routes that connect in one or more metal layers the semiconductor device components according to their logical connections, the determination being based at least in part on a plurality of predefined tracks associated with a metal layer; and outputting at least a portion of the route information. A first portion of the plurality of predefined tracks corresponds to a first color and a second portion of the plurality of predefined tracks corresponds to a second color.
