Systems, methods, and apparatus for operating an integrated circuit (IC) are provided. An apparatus may be configured to receive at one or more switches a signal from at least one circuit positioned on a first die lying within a first geometric plane, detect a signaling path between the at least one circuit positioned on the first die and at least one circuit positioned on a second die lying within a second geometric plane that is different from the first geometric plane, and control the one or more switches to route the signal along the signaling path. Circuits having a similar power characteristic are positioned adjacent to each other on the first die or the second die and circuits having a high temperature characteristic are positioned separate from each other on the first die or the second die.
