Signal Propagation in High Speed Differential Transmission Line Using Parallelized Finite-difference Time-domain Method

|This paper presents the investigations in the electric performance of di¬erential signalling transmission lines used for high speed integrated circuits (IC’s) and boards by using the parallelized ­ nite-di¬erence time-domain (FDTD) method. The FDTD method is ­ rstly parallelized with single-program multipledata (SPMD) architecture using the MPI protocol and experimentally validated. The key electrical factors, crosstalk, impedance of highspeed di¬erential transmission lines, are simulated and investigated for various con­ guration using the developed parallelized FDTD code. The discussions presented in this paper shall be used a guideline for engineers to optimize high-speed circuit designs with di¬erential signaling transmission lines for signal integrity (SI) and electromagnetic compatibility (EMC). y Also with Department of Electrical and Computer Engineering, National University of Singapore, Kent Ridge, Singapore 119260 z Also with High Performance Computation of Engineered Systems (HPCES) Programme of Singapore-MIT Alliance (SMA), Singapore
