Inaccuracies in partial elements computation, even at very high frequencies, may generate late time instabilities. On the other side, accurate computation of partial elements becomes prohibitively cumbersome when performed at high frequencies. In this paper a macro- modeling technique is applied, which is based on the use of frequency derivatives to allow a broadband characterization of electric and magnetic field couplings at a reduced computational cost.","PeriodicalId":206352,"journal":{"name":"2007 IEEE Workshop on Signal Propagation on Interconnects","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115140157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, system-wide modeling of high-speed interconnects using conventional circuit simulators such as SPICE can become prohibitively CPU expensive. We propose to formulate analytical interconnect macromodels capturing noise effects, and to integrate them into the SystemC communication abstractions. Experimental results show that HDL simulations achieve an average accuracy of 5% from SPICE, while a few case studies illustrate the applicability of the proposed framework for fast exploration of physical channel configuration and performance estimation.","PeriodicalId":206352,"journal":{"name":"2007 IEEE Workshop on Signal Propagation on Interconnects","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125438100","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is done to evaluate signal integrity such as crosstalk, propagation delay and rise time on a set of several unintentionally coupled Cu lines of micron and nanometer sizes. A full wave analysis based on tangential vector finite element method is implemented in MATLAB environment in order to extract, via a transmission multicoupled line model, the electrically R, L, C, G, Lm, Cm coupled elementary cell. This model with all the mutual impedance and admittance is necessary and more convenient for transient analysis by using commercial software such as Spice or other transient tool. We show that the improvement due to the introduction of low dielectric material can reach more than 200% for the crosstalk and 25% on propagation delay for 1 mm interconnect length. This work also highlights that it is not always realistic to study only a set of two or three lines because some signals appears at the far end of the second or the third interconnect located at the both sides of an attacker.","PeriodicalId":206352,"journal":{"name":"2007 IEEE Workshop on Signal Propagation on Interconnects","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129300324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently the digital signals into play reach data rates of some Gbps with rise/fall times of few picoseconds. In this context it is important to correctly characterize the transmission lines on boards for studying the signal propagation as a function of the frequency. The more effective technique starts from measurements, connecting the studied traces to the measurement instruments by means of transition networks or fixtures. But in this case the connective errors due to the connector mismatches and discontinuities have to be removed. The paper proposes different mathematical de- embedding procedures to evaluate the propagation constant of differential traces, de-embedded by the effects of the SMA's connecting them to the VNA.","PeriodicalId":206352,"journal":{"name":"2007 IEEE Workshop on Signal Propagation on Interconnects","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131426637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
