Abstract
This thesis mainly focuses on the analysis of design and signal integrity issues involved in high-speed electrical link components including differential-pairs, multichannel connectors, and cables. The main purpose of this research is to work through high-speed component and system signal integrity analysis, address the key problems confronted in each design-and-analysis stage, and further develop validated express tools. FEM (Finite element method) simulators were used to analyze field distributions, examine S-parameter results at electrical ports, and investigate parasitic effects for electrical link components with arbitrary 3D geometries. Design optimization was reached with the design parameter sweeps. A faster simulation was developed using distributed-lumped subcomponent transformation. Signal integrity diagnoses were enabled via integration of 3D modeler and 2D schematics or layout, S-parameter analysis, channel simulation with TX/RX equalization, pre-emphasis, encoding, and crosstalk setup. Test-fixture de-embedding and embedding were used to improve the correlation between simulation and measurement on the device-under-test (DUT) model. With effort on investigating design and validation on components and system, the signal integrity workflow on high-speed electrical links was better understood and will be further utilized to improve the performance of millimeter-wave systems.
