Abstract

Accurate time domain analysis and cross talk estimation in VLSI interconnects has emerged as an essential design criteria. This paper presents the description of a finite difference time domain (FDTD) method that is intended for estimation of voltages and currents on coupled transmission line. A numerical method based on FDTD is opted for the estimation of cross talk induced time delay in lossy RLC interconnects. Both functional and dynamic cross talk effects in coupled line configuration are analyzed. Effect of line resistance on delay is also evaluated. A linear resistive driver is used to drive distributed RLC transmission line for lossy interconnect. It has been observed that the analytical results for proposed FDTD model are in good agreement with HSPICE simulation results. The proposed model using FDTD results in an average error of 4.1% with respect to HSPICE.

用FDTD方法分析RLC模型互连中的动态串扰

在超大规模集成电路互连中，精确的时域分析和串扰估计已成为必不可少的设计准则。本文介绍了一种时域有限差分(FDTD)方法，用于估计耦合传输线上的电压和电流。采用基于时域有限差分的数值方法估计有耗RLC互连中串扰时延。分析了耦合线路结构中的功能串扰效应和动态串扰效应。并对线路电阻对延迟的影响进行了评价。采用线性电阻驱动器驱动分布式RLC传输线，实现有损互连。结果表明，时域有限差分模型的分析结果与HSPICE仿真结果吻合较好。所提出的FDTD模型相对于HSPICE的平均误差为4.1%。
