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. The simulation tool is working properly and matches the result form other software and measurement tool, such as CST. It provides S-parameters, and wave propagation monitoring to assist engineers for analyzing signal integrity of a PCB for high speed circuits. The FDTD calculates the 3-D electromagnetic propagation numerically in the structure of a printed circuit board (PCB). Adaptive mesh refinement of untuned filter 3. Tuning Step 30 Lines/Lambda 51000 cells TD (AR) Solver time: 256 s Resonant (MOR) Solver 91 s Accuracy: PBA slight readjustedment of only one parameter by 0.0125mm 1. This thesis work developed a simulation tool for characterizing high speed circuit, using Finite Difference Time Domain (FDTD) method. FEM FDTD FIT+PBA CST Competitors CST MWS 1.0. Accurate simulation of electromagnetic wave propagating in the circuits becomes critical in today’s design cycle for high speed devices.

As frequency increases, signal integrity may decrease to a point where the system or device fails. With increasing demands on high-quality and fast communication, circuit design for high speed signaling becomes more important than ever. Its transient solver is a native time solver and a Fourier. High speed signaling over a significant length is an important issue for high speed electronic devices such as Ethernet network routers. Hello Aman, Actually I think the best EM simulator for FDTD is CST Microwave studio because: 1.
