随着工艺技术到达深亚微米领域，互连线的耦合电容、电感对电路的影响越来越大。为
了有效地捕捉互连线的影响，需要进行精确地电路级模拟，但是从版图自动提取出来的互连
线通常是一个大的线性电路。利用spice 模拟器来模拟，通常效率比较低下。针对线性电路
的特点，人们通常采用降阶模型来建模，提出了许多降阶模型方法。本文将介绍各类降阶模
型方法，分析它们的原理，比较它们的优缺点。-With the technology arrived in the area of deep sub-micron, interconnect coupling capacitance and inductance of the circuits are increasingly affected. In order to effectively capture the impact of the interconnection line, the need for accurate circuit-level simulation, however, automatically extracted from the territory of the interconnection line is usually a large linear circuit. Simulator to simulate the use of spice, usually relatively low efficiency. For linear circuit characteristics, it is usually reduced-order model to model, put forward a number of reduced-order model. This article will introduce the various types of reduced-order model, analysis of their principle, comparison of their advantages and disadvantages.
