随着系统频率的不断提高,许多影响系统性能的噪声就会出现,造成系统性能的下降,信号完整性问题变得越来越严重。串扰就是一个经常遇到的问题,而引起串扰的根本原因就是边缘场导致攻击线和受害线之间产生容性耦合和感性耦合。在对引起串扰的原因进行分析的基础上,介绍了利用二维场求解器求解单位长度电感和电容矩阵的方法,在求得单位长度电感和电容矩阵以后,就可以建立传输线的SPICE电路模型,对电路系统的信号完整性进行研究。
隨著繫統頻率的不斷提高,許多影響繫統性能的譟聲就會齣現,造成繫統性能的下降,信號完整性問題變得越來越嚴重。串擾就是一箇經常遇到的問題,而引起串擾的根本原因就是邊緣場導緻攻擊線和受害線之間產生容性耦閤和感性耦閤。在對引起串擾的原因進行分析的基礎上,介紹瞭利用二維場求解器求解單位長度電感和電容矩陣的方法,在求得單位長度電感和電容矩陣以後,就可以建立傳輸線的SPICE電路模型,對電路繫統的信號完整性進行研究。

With the constant improvement of the system frequency , many noise appeared , which can cause the deterioration of the system performance and make the signal integrity problems to become more and more serious . Crosstalk is a frequently encountered problem ,which is caused by the capacitive coupling and the inductive coupling as the reason of edge filed generated between aggressive lines and victim lines .On the basis of the analysis of the causes of crosstalk ,this paper introduced how to use a 2D field solver to solve per unit length inductance and the capacitance matrix so as to establish the SPICE circuit of transmission lines and analyze the signal integrity of multiple conductor transmission line system .
