This is mainly due to the overheads associated with incorporating defect tolerance and re-configuration circuitry into large and complex designs. The WASP series of monolithic wafer scale massively parallel computers have overcome many of these obstacles by adopting a hierarchical defect tolerance strategy. The paper presents an analysis of the effect of defect clustering on the target WASP device yields. The yield model uses extrapolated parameters from earlier WASP devices. and assumes a 0.7 /spl mu/m process. The results show that the target WASP yield predictions are generally very high, and largely independent of defect clustering. However, for high defect densities and high harvest requirements, the predicted yields vary considerably depending on the degree of defect clustering.<<ETX>>","PeriodicalId":183733,"journal":{"name":"Proceedings of 1994 International Conference on Wafer Scale Integration (ICWSI)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127955264","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 chip features all the logic required for the global test and configuration of a coarse-grained MIMD multiprocessor system. These structures are implemented on the 16 cm/sup 2/ Large Area Integrated Circuit 1 (LAIC 1). This chip utilizes different redundancy and reconfiguration concepts: 1) A defect-tolerant configuration network provides the connections of the modules. 2) System access is provided by a multiple-defect tolerant unidirectional scan path. 3) A repair of the primary I/O-buses is performed by programming laser fuses and anti-fuses. 4) The use of TMR for system clock and dual-rail signals for control lines enables an initial access to the system without laser repair. The results presented in this paper show, that all the proposed redundancy and reconfiguration concepts together provide a suitable scheme for the test and configuration of a large area chip containing coarse-grained modules with high module connectivity. These schemes have been proven to work even under adverse conditions such as large defects and high defect densities.<<ETX>>","PeriodicalId":183733,"journal":{"name":"Proceedings of 1994 International Conference on Wafer Scale Integration (ICWSI)","volume":"340 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134153782","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 emerging technology of 3D-WSI offers a way of meeting this challenge, giving the potential for step-function increases in parallelism using existing WSI package options. It also permits independent scaling of I/O, parallel processing power and control, leading to a degree of cost-effectiveness that 2D-WSI cannot match.

No assumption is made on the class of DFGs considered (i.e. iterative or general) thus allowing the description of any algorithm. Balancing of DFGs where nodes represent computational activities whose exchange of information is not self synchronised is a convenient way to raise the throughput of the graph (architecture). This paper presents a methodology that allows balancing acyclic and cyclic data flow graphs optimizing both latency and throughput.<<ETX>>","PeriodicalId":183733,"journal":{"name":"Proceedings of 1994 International Conference on Wafer Scale Integration (ICWSI)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127963583","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}

Yet it is possible to overcome these drawbacks and offer engineers a finite element based design tool for rapid design evaluation by simply applying proven artificial intelligence technology, feature based modeling and object oriented techniques to streamline and automate the finite element modeling and analysis as much as possible. Finally, the concepts espoused by Taguchi and others for high quality manufacturing processes can also be applied to advanced package design in a computer based environment. In this manner the design space for advanced package design can be efficiently explored early in the design process and the most promising package configuration in terms of performance and robustness can be selected for prototyping and testing. The authors propose a computer based design tool for multichip modules which embodies these ideas.<<ETX>>","PeriodicalId":183733,"journal":{"name":"Proceedings of 1994 International Conference on Wafer Scale Integration (ICWSI)","volume":" 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120828492","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}

FERMI is being designed to satisfy the extreme requirements set by calorimeters in the next generation of particle physics detectors. Such detectors are being designed for the future LHC and SSC accelerators at CERN in Switzerland and at the SSC-laboratory in Texas. The calorimeters demand frequent (67 MHz for LHC, 63.5 MHz for SSC) high precision sampling of a large number of input channels (about 5x10/sup 5/). Each FERMI module serves 9 channels from which samples are AD-converted, corrected and temporarily stored in a local memory. The data is also merged into a trigger sum processed by digital filters to recover time of incidence and amplitude of incoming pulses. Such data is then fed to a first-level trigger processor which screens irrelevant information. Only data that may contain interesting information is kept for further analysis. Arrays of 50000 FERMIs constitute formidable processing systems when considering the total computational power and storage capacity.<<ETX>>","PeriodicalId":183733,"journal":{"name":"Proceedings of 1994 International Conference on Wafer Scale Integration (ICWSI)","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126777859","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}
