Abstract

"Signal integrity (SI) and power integrity (PI) play an important role in the modern high-speed digital system design, which are closely related to the printed circuit board (PCB) dielectric material property, the PCB interconnect performance, and the power delivery network (PDN) on PCB. Generally, the full-wave simulation is used to accurately analyze and evaluate the designed PCB. But full-wave simulation is not a good option for the complex PCB structure with high aspect ratio, for example, PCB vias, and PDN, which will require significant computing time and storage resources. Equivalent circuit models have been developed to efficiently predict the electrical performance of those complex PCB structures. To get the accurate and time-efficient signal integrity and power integrity modeling and analysis of high-speed digital systems, some works related to the PCB dielectric material characterization, the high-speed PCB via modeling, and the on-chip PDN impedance modeling have been done in the paper. The paper can be categorized into three parts, PCB material characterization based on cylindrical cavity resonator (CCR), high-bandwidth and high-accuracy physics-based circuit model of high-speed PCB via, and on-chip PDN impedance model based on layer Green’s function and partial element equivalent circuit (PEEC). In part I, the CCR apparatus is designed and manufactured to measure the PCB dielectric liquid permittivity. The physics-based equivalent circuit model of the high-speed PCB via is detailed in part II. The equivalent circuit of PCB via is extracted based on the mode-decomposition and domain-decomposition theory. An equivalent circuit model based on layer Green’s function and PEEC is proposed to efficiently predict the impedance of the on-chip PDN in part III" -- Abstract, p. iv
