摘要: | 隨著高速數位電路的設計趨勢朝向高頻率操作,高功率密度,低功率消耗及體積更小,因此維持電路系統的訊號完整度和電源完整度成為設計上的一大挑戰,而串音及同時切換雜訊的產生造成訊號傳輸品質的不良及電源供應穩定的問題,影響電路運作的表現。
本論文使用傅立葉轉換快速建立三維晶片內直通矽晶連通柱陣列的等效簡化電路模型。直通矽晶連通柱在晶片中扮演訊號/電源/接地其中之一的功能,若將每一根直通矽晶連通柱與其它根直通矽晶連通柱彼此間的耦合效應皆納入考慮,對建立等效電路及電路分析都將相當耗時。而耦合效應隨著距離衰減,當距離大到達某一程度時,耦合效應將衰減到可忽略的程度,因此根據此一隨距離衰減的特性,對多根直通矽晶連通柱建立簡化的等效電路模型,進而分析在任意訊號/電源/接地擺置的情況下,直通矽晶連通柱陣列間的串音及計算同時切換雜訊峰值,藉以達到簡化電路預測的目的。 With the design trends of high clock frequencies, high power density, low voltage levels, and small size in the development of the high-speed digital systems. the issues of crosstalk and simultaneous switching noise (SSN) in the high-speed digital systems are getting more and more important. In this paper, a design methodology based on the two--dimensional Fourier transform is proposed to attain a simplified through-silicon via (TSV) equivalent circuit. TSVs may be assigned to be the signal/ground/power net in a chip and there are the coupling effects between any of two TSVs. It is time-consuming to attain an equivalent circuit for analyzing the circuit by the traditional methods because all the coupling effects between any of two TSVs are considered. To improving this problem, the distance decay characteristic of coupling effects is considered in attaining the equivalent circuits. By ignoring the coupling effects between two TSVs with the far enough distance can be ignored, a simplified equivalent circuit can be attained. With the proposed simplified equivalent circuit, the crosstalk and SSN in a chip, whose TSVs are randomly assigned with the signal/ground/power ratios state, can be estimated. |
