The solution procedure is implemented in a recursive manner by using the exponential approximation.

Given the reduced signal swings on the external buses the required modeling accuracy is now on the order of tens of picoseconds and tens of millivolts. As such many of the electromagnetic modeling techniques developed for high end supercomputer systems are quickly finding their ways into the PC industry. On the other hand, unlike high end systems, the key to the success of any high volume design is its cost effectiveness. In this paper, a Monte Carlo design and modeling approach to high volume high speed transmission line systems is presented. The sensitivity of the accuracy of any design parameters to the overall system performance is evaluated in terms of its effects on the statistical distribution of the optimized parameters or yield. It is shown that the traditional \"worst case\" design can be very misleading and under-estimates the worst case. We also show that the uncontrolled nature of the design makes it virtually impossible to find a \"representative\" signal and therefore detailed analysis of any given signal is only useful in determining the accuracy of the simulations or the phenomena that effect the results, but not the robustness of the entire system.","PeriodicalId":253331,"journal":{"name":"Proceedings of Electrical Performance of Electronic Packaging","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134351203","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}

This is due to the fact that at and below 0.5 micron ground rules, metal line cross-sections are becoming so small that lossy line propagation performance degraders are becoming significant. This knowledge was garnered by analyzing a real microprocessor design and comparing this data with a theoretical wiring model. However, the use of a multi-chip die (MCD) rather than an oversized die can result in a significant cost-performance advantage for a large complex system function such as a microprocessor.","PeriodicalId":253331,"journal":{"name":"Proceedings of Electrical Performance of Electronic Packaging","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130393861","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}

For the sub-nanosecond rise/fall times and over 100 MHlz clock rates used in aggressive digital designs, the signal bandwidth ranges up to 3 to 5 GHz. Distributed networks, such as power and ground planes in MCWCB's, can no longer be accurately represented by simple models of a few lumped elements in the high frequency region. On the other hand, full-wave rigoirous electromagnetic field solulions [4] become impractical for complex digital circuit simulation due lo the extremely high computational requirement, and the difficulty of integration with the circuit type of simulations used in most digital designs. In this paper we present an efficient and accurate approach for analyzing and modeling of complex structures, and for predicting their signal integrity characteristics in MChWCB systems. The focus is to develop a fast, flexible and easy to use simulation tool with a clear circuit interpretation so it can be conveniently integrated with existing CAD tools and circuit simulators for IC mid system designers without getting into electromagnetic details. It can also handle the complexity of real MCM/PCB designs within practical computational constraints of an engineering workstation. Simulated results are presented for various interesting and important structures. Signal integrity characteristics siuch as switching noises, ground Ibounces, crosstalk, waveform distortions, arid delays, are analyzed for practical applications.","PeriodicalId":253331,"journal":{"name":"Proceedings of Electrical Performance of Electronic Packaging","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116912799","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}

The frequency domain technique is based on using the modal analysis to suppress the natural resonances of multi-conductor transmission line networks. Once a network is optimized in the frequency domain, the optimized worst case timing and signal integrity parameters, based on which the maximum operating speed is determined, are computed in the time domain. Finally, to demonstrate the accuracy of technique, several numerical examples of multi-conductor networks are presented.
