Abstract :
In this paper, we address the analysis and design problems for power distribution networks (PDNs) in 3D ICs. An on-chip current distribution model is proposed to identify the unique noise behaviors of 3D PDNs. Based on the model, an analysis flow is designed for 3D PDNs in both frequency domain and time domain. With the analysis flow, the global and local resonance phenomena that are distinct in 3D PDNs are discovered. The physical mechanisms of the resonance are investigated and techniques for robust 3D PDN design are proposed.
