Open defects on wiring lines and short defects between adjacent two wiring lines in links are assumed for defects in INs. The basic idea of the proposed design is to add redundant wiring lines and switches into each physical link. The three schemes are compared by evaluating yields when they are applied to hypercube networks. As a result, one scheme is superior to others, and an effect of defect-tolerant design by the scheme is effective and useful for six and eight dimensional hypercubes.","PeriodicalId":213798,"journal":{"name":"Proceedings of 1993 IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133421145","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}

Block implementation of fault-tolerant LMS adaptive FIR filters 块实现的容错LMS自适应FIR滤波器

Redinbo","doi":"10.1109/DFTVS.1993.595607","DOIUrl":"https://doi.org/10.1109/DFTVS.1993.595607","url":null,"abstract":"Adaptive FIR filters are widely used in a variety of modern digital signal processing application, and with the advancement in VLSI technology, it is now feasible to build fairly complicated multiprocessor systems which can provide the necessary computational power required by some highly demanding real-time signal processing applications. The increased computational power of such systems also makes fault tolerance an even more important issue that needs to be addressed carefully, because a single hardware failure can easily render the whole compuational results useless. Algorithm-based fault tolerance (ABFT), recently developed as an effective high level fault-tolerant technique, employs, in addition to the normal outputs, parity numbers that are related to the outputs. These parities can be used to concurrently detect, and in some cases correct, errors caused by hardware failures. A highly efficient implementation of the encoding scheme based on the weighted checksum code is proposed. It is particularly suitable for block adaptive signal processing, and the computational efficiency of this method is compared with that of the more general weighted checksum code.","PeriodicalId":213798,"journal":{"name":"Proceedings of 1993 IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125430606","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}

An interactive yield estimator as a VLSI CAD tool 作为VLSI CAD工具的交互式良率估计器

Koren","doi":"10.1109/DFTVS.1993.595763","DOIUrl":"https://doi.org/10.1109/DFTVS.1993.595763","url":null,"abstract":"The yield of a VLSI chip depends, among other factors, on the sensitivity of the chip to defects occurring during the fabrication process. To predict this sensitivity, one usually needs to compute the so-called critical area (A/sub c/) which reflects how many and how large the defects must be in order to result in a circuit failure. The main computational problem in yield estimation is to calculate A/sub c/ efficiently for complicated, irregular layouts. A novel approach is suggested for this problem that results in an algorithm to solve it efficiently. This algorithm is compared to other yield-prediction methods, which use either the Monte-Carlo approach (VLASIC) or a deterministic approach (SCA), and is shown to be faster. It also has the advantage that it can graphically show a detailed defect sensitivity map that can assist a physical designer in improving the yield of his/her layout.","PeriodicalId":213798,"journal":{"name":"Proceedings of 1993 IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems","volume":"34 8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123516777","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 this, an IC defects-based analysis is used to study the impact of catastrophic faults on basic CMOS analog blocks. The impact on circuit behavior is analyzed for functional test and for i/sub DD/ power supply fault signatures. It is also demonstrated that a significant part of catastrophic faults cause out of specs performance, and may thus decrease the yield of the product, by an apparent parametric yield degradation. Finally, it is shown that layout level DFT (design for testability) can be rewardingly used to increase test confidence and product quality.","PeriodicalId":213798,"journal":{"name":"Proceedings of 1993 IEEE International Workshop on Defect and Fault Tolerance in VLSI Systems","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133274579","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}
