碩士 === 國立中央大學 === 電機工程研究所 === 91 === In this thesis, we first introduce some electrical design automation (EDA) tool such as Ansoft Q3D Extractor and propose a new analytic method, which divide the package into small component and use W-element distributed model for the simulation. This method is suitable to explore the influence of package on high-speed digital signal. Second, moment matching technique (MMT) is used to improve the simulation efficiency. But there are some problems in MMT. When the length of lossy transmission line increases, the accuracy will deteriorate. In this thesis, we propose a new distributed transmission line model for MMT to shorten the complicated process. Besides, we also prove it in mathematics. For the case with 0.3m transmission line, to a demand on RMS error of less than 0.0046V, one method (modified MMT) needs only 6 poles and 1 hop while the original MMT requires 11 poles and 11 hops. For the same number poles (6 poles), the error of MMT is 0.0165V and modified MMT is 0.0042V. For the case with 0.5m transmission line, to a demand on RMS error of less than 0.0027V, one method (modified MMT) needs only 5 poles and 1 hop while the original MMT requires 19 poles and 17 hops. For the same number poles (5 poles), the error of MMT is 0.0371V and modified MMT is 0.0027V.
