At this range of frequency this work shows that an Alumina MCM implementation has 17% less cost performance. In addition, the trend curves shown in this study indicate that polyimide thin film MCM structures will be the best cost performers in future systems where the off chip bus speeds exceed 250 MHz.","PeriodicalId":220951,"journal":{"name":"Electrical Performance of Electronic Packaging","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130227535","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}

In the last several years, very fast MoM solvers have been developed by sparsifying the dense system using a hierarchy of multipole expansions or grid projection plus the fast Fourier transform. The hierarchical multipole algorithms represented clusters of source distributions with an expansion in the center of the cluster, where as grid projection algorithms represent clusters using grid-locked point sources. In this paper we consider how to improve the efficiency of either algorithm by using grid-locked multipole expansions to represent clusters of sources.","PeriodicalId":220951,"journal":{"name":"Electrical Performance of Electronic Packaging","volume":"19 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116801346","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}

On-chip interconnect must be accounted for at all levels of the design hierarchy, starting with synthesis, through physical design and ending with verification. Each level of the design hierarchy brings its unique challenge to interconnect modeling. Decisions made at the synthesis level have the greatest influence on the final interconnect design, yet one must deal with the uncertainty of having no physical design at this stage. During physical design, the uncertainty gradually decreases as the layout takes shape while the accuracy requirements on the interconnect models become more demanding. At the post-layout verification stage, there are no physical uncertainties. However for final verification, the fact that interconnect plays a dominant role in all performance parameters of the design, i.e., power, system delay, area and signal integrity, necessitates the use of extremely accurate interconnect models. This paper focuses on on-chip interconnect modeling technologies for post-layout verification (often called \"parasitic extraction\") and characterization/silicon-correlation which is essential to interconnect modeling at all levels. The state-of-the-art in \"parasitic extraction\" is reviewed and strengths and shortcomings are discussed. The need for establishing correlation with silicon is emphasized. Various popular measures of accuracy are scrutinized and the concept of accuracy in performance variables is introduced. Finally, the impact of interconnect modeling error on performance and signal integrity verification is discussed.","PeriodicalId":220951,"journal":{"name":"Electrical Performance of Electronic Packaging","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126221629","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}
