  2. 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

  4. An algorithm to resolve the coupling effect problem is proposed during the cross point assignment ( cpa ) stage. in the algorithm, the priority queue concept and the rip - up and reroute strategy are combined to control crosstalk noise caused by interconnect coupling capacitance. first, the nets are arranged into different priority queues according to their weighted sum of their length and criticality. then, the cpa problem for one queue of nets is translated into a linear assignment problem. after the assignment of one queue of nets, a post - cpa checking routine is performed to check and rip up the net pairs which violate the crosstalk noise constraint and then push them into the next queue to be reassigned. the algorithm is tested by a set of bench mark examples, and the experimental results are promising

  6. A algorithm is presented to identify dynamic crosstalk noise. in the course of dynamic crosstalk noise identification, hybrid timing analysis is used to provide accurate signal arrival time, which can provide more accurate timing information than static timing analysis. at the same time, a novel test generation is chosen to verify the correlation of signals. so dynamic crosstalk noise can be identified by these accurate timing and logic information

    提出了動態串擾噪聲的識別演算法.針對基於傳統靜態時序分析的結果過于保守的缺點,本演算法引入了混合時序分析,縮小了時間窗區間,為動態串擾噪聲的識別提供了準確的時序信息,與此同時,通過測試生成來驗證信號間的邏輯關系,根據這些準確的時序及邏輯信息,識別出動態串擾噪聲
  7. For recent years, adsl has world widely employed and widely used in many aspects such as vod, remote medical treatment and e - shopping etc. but we noticed that the traditional telephone networks are designed for the transmission of low frequency signals, and the adsl ' s frequency rang is from 0 to 1. 104mhz, so we must confront the signal attenuation, the loop line noise impairments, the crosstalk interferences, the bridge tap reflections and the rf disturbances problems and many other problems when transmitting the adsl signals one the telephone networks

    近幾年來, adsl在世界范圍內得到充分的使用,廣泛應用於視頻點播、遠程醫療、網上購物等各個方面。但是由於電話線網路是專門為傳輸低頻信號而設計,而adsl的頻譜范圍在0 1 . 104mhz內,因此在傳輸adsl信號時,面臨著信號衰減、線路噪聲、串音干擾、橋接抽頭反射和射頻干擾等等多方面的問題,這就要求在adsl開通之前對線路進行一系列的測試。
