FDTD-Based Statistical Analysis of Crosstalk on Planar Data buses

Crosstalk is a major limiting factor of signal quality and important EMC problem in high speed communication systems especially when fast data buses involved such a data bus is considered as a planar multiconductor transmission line. This paper will demonstrate how the finite difference time domain (FDTD) method provides an exact solution of the transmission-line equations to analyze the near end and the far end crosstalk. In addition, this study makes it possible to analyze pulse sources connection at the input according to random occurrences in order to closely approach real cases accurately. The paper also discusses a statistical analysis, based upon a set of several simulations. Such analysis leads to a better understanding of the phenomenon and yields useful information.
