Design automation scheme for wirelength analysis of resonant clocking technologies

Resonant clocking technologies have been gaining increased attention due to their superiority of clock frequency, power dissipation, and variation tolerance. Two of the resonant clocking technologies, standing wave and rotary clocking, require specialized clock routing procedures to accommodate grid-type distribution topologies and the tapping of registers onto these grids. The total tapping wirelength for both technologies are significant due to the impacts on power dissipation and routing congestion. A quantitative study is performed to compare the total tapping wire lengths for equivalent implementations of these two resonant clocking technologies. Experiments demonstrate that the standing wave technology (with mobius implementation) requires on average 3.99X less tapping wirelength compared to the rotary resonant clocking technology.
