1. A device, comprising:
first track groups on a first conductive layer of an integrated circuit, each of the first track groups including at least one of a different first track group pitch, a different first track group spacing, and a different first track group width than the other first track groups,
wherein each of the first track groups includes first tracks that have a different first track width than the first tracks in the other first track groups on the first conductive layer and that define a different first track pitch than the first tracks in the other first track groups on the first conductive layer; and
second track groups on a second conductive layer of an integrated circuit, each of the second track groups including at least one of a different second track group pitch, a different second track group spacing, and a different second track group width than the other second track groups,
wherein each of the second track groups includes second tracks that have at least one of a different second track width and a different second track spacing than the second tracks in the other second track groups.
