Three research issues in high-performance VLSI system design are being addressed: (1) how to relate the system performance function, characterized by electrical parameters, to the geometrical parameters of the VLSI physical design; (2) how to model performance driven VLSI physical designs based on given technology and computational capability; and (3) how to characterize the fundamental computational aspects of modeled problems and develop effective algorithms for solving them. A distributed RLC circuit model for interconnects is being designed. It considers: non-monotone circuit response, coupling effect among the signal lines, and low energy consumption. Efficient computation methods that solve time-varying Maxwell equations using the adaptive wavelet collocation method (AWCM) are being devised. The algorithms and methods are being included in a CAD system.

高性能VLSI系统设计中的三个研究问题是：（1）如何将以电学参数为特征的系统性能函数与VLSI物理设计的几何参数联系起来：（2）如何根据给定的工艺和计算能力，建立性能驱动的VLSI物理设计模型;以及（3）如何描述建模问题的基本计算方面并开发有效的算法来解决它们。 设计了一种互连线的分布式RLC电路模型。 它考虑了电路响应的非单调性、信号线间的耦合效应和低能耗等问题。 利用自适应小波配置法求解时变麦克斯韦方程组的有效计算方法正在被设计出来。 该算法和方法已被纳入CAD系统中。
