3. 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
   目前也有一些針對這些噪聲的高速pcb板級仿真軟件,但它們都缺乏詳盡的建模能力,特別是當頻率逐漸提高和電路板日益復雜后,更是顯得無能為力,要精確地對互連結構進行分析,三維全波仿真器似乎不可缺少,其缺點就是速度慢,對整板仿真很難實現(xiàn),但非常適用于規(guī)則開發(fā),而這正好是本文除了建模與仿真方法研究外另一個重點。
