高速芯片封装结构的同步开关噪声分析及抑制 - This dissertation only considers the signal ’ s distortion by interconnect , such as delay , reflection , discontinuity of microstrip , crosstalk and simultaneous switching noise , and so on . nowadays , there are some simulation software in pcb level , but they are lack of the well ability of modeling . in order to simulate the interconnect accurately , we have to make use of three - dimension full wave analysis method , whose disadvantage is low speed in computing , but is competent for developing rules in high - speed designs
目前也有一些针对这些噪声的高速pcb板级仿真软件,但它们都缺乏详尽的建模能力,特别是当频率逐渐提高和电路板日益复杂后,更是显得无能为力,要精确地对互连结构进行分析,三维全波仿真器似乎不可缺少,其缺点就是速度慢,对整板仿真很难实现,但非常适用于规则开发,而这正好是本文除了建模与仿真方法研究外另一个重点。 - First , the dissertation introduces transmission line theory , analyzes si in the design of high speed pcb , including reflection , crosstalk , simultaneous switch noise etc in detail . secondly , the dissertation simulates the reflection and crosstalk of the given circuit models using hyperlynx , the eda software of mentor corporation , and shows the waveforms of reducing reflection by adding terminators and the waveforms of the crosstalk influenced by changing the parameters of transmission lines . at last the dissertation summarizes the solutions to reducing reflection , crosstalk and ssn , and introduces the design flow of high speed pcb based on si
