Abstract

High speed signaling over a significant length is an important issue for high speed electronic devices such as Ethernet network routers. With increasing demands on high-quality and fast communication, circuit design for high speed signaling becomes more important than ever. As frequency increases, signal integrity may decrease to a point where the system or device fails. Accurate simulation of electromagnetic wave propagating in the circuits becomes critical in today’s design cycle for high speed devices. This thesis work developed a simulation tool for characterizing high speed circuit, using Finite Difference Time Domain (FDTD) method. The FDTD calculates the 3-D electromagnetic propagation numerically in the structure of a printed circuit board (PCB). It provides S-parameters, and wave propagation monitoring to assist engineers for analyzing signal integrity of a PCB for high speed circuits. The simulation tool is working properly and matches the result form other software and measurement tool, such as CST. This thesis introduces signal integrity, numerical method for simulating electromagnetic propagation, design and development a FDTD tool for circuit simulations, and validation results of the tool.
