3.2. Signal Transmission on Chip

We consider now on-chip communication and its abstraction as a micronetwork. We analyze the physical layer of the micronetwork stack in this section. Wires are the physical realization of communication channels in SoCs. (For our purposes, we view busses as ensembles of wires.) Even though components may be hierarchically designed, we shall focus on components and their interconnection with global wires. We neglect the internals of components and their wiring by local wires, because the properties of such wires can be made to scale with the technology, and it is likely that present design styles and methods will still apply [86].

Global wires are the physical implementation of ...
