Abstract

Analytical models Clocks Computational modeling Inductance Integrated circuit modeling Modeling Power transmission lines Resonant Clocking Simulation Topology
Resonant rotary clocking is a low power-high speed clock distribution technology for the modern VLSI circuits. Alternative topological implementations of rotary clocking with non-regular custom rings have been proposed in literature. In this paper, the impact of parasitics of the non-regular topo-logical geometries on the rotary operating characteristics is presented. In particular, partial element equivalent circuit (PEEC) analysis is used to show that the corner geometry in a custom ring increases the mutual inductance approximately by 80%. Also, SPICE simulations are performed where the parasitics due to the topological factors are incorporated for an 8% increased accuracy in simulation. Further, the power dissipation on the rotary ring is analyzed with varying number of corners. When tested with the IBM R1-R5 benchmark circuits, the total power dissipated on a custom ring (corners between 4 and 12) is within ±5% of the total power dissipated on a regular ring(4 corners).
