From our observation during the manufacturing test, multiple stuck-at faults often exist in the failed chips during the yield ramp-up. Therefore the authors propose a method for diagnosing multiple stuck-at faults based on the compressed responses from BIST. The fault diagnosis based on the compressed responses from BIST was called the post-BIST fault diagnosis (Takahashi et al., 2005, Takamatsu, 2005). The efficiency on the success ratio and the feasibility of diagnosing large circuits are discussed. From the experimental results for ISCAS and STARC03 (Sato et al., 2005) benchmark circuits, it is clear that high success ratios that are about 98% are obtained by the proposed diagnosis method. From the experimental result for the large circuits with 100K gates, the feasibility of diagnosing the large circuits within the practical CPU times can be confirmed. The feasibility of diagnosing multiple stuck-at faults on the post-BIST fault diagnosis was proven","PeriodicalId":113870,"journal":{"name":"2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127685108","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 nanometer-scale VLSI processes (45 nm and below), it is difficult to guarantee correct fabrication with an acceptable yield without employing design techniques that take into account the intrinsic existence of manufacturing defects. In order to improve the yield and reliability of multi-core SoCs, their interconnect infrastructures must be designed such that fabrication and life-time faults can be tolerated. In this work we present a self-repair method for the interconnect fabrics of integrated multi-core systems. Our method is based on the use of redundant links and crosspoints, and improves both post-manufacturing yield and life-time reliability of on-chip communication fabrics. Our method can provide a significant interconnect yield improvement (up to 72% in our experiments), and allows fine-tuning of yield versus redundant components","PeriodicalId":113870,"journal":{"name":"2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132645739","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 conventional soft error tolerant methods for soft errors on the combinational parts do not provide enough high soft error tolerant capability with small performance penalty. This paper proposes a class of soft error masking circuits by using a Schmitt trigger circuit and pass transistors. The paper also presents construction of soft error masking latches (SEM-latches) capable of masking transient pulses occurring on combinational circuits. Moreover, experimental results show that the proposed method has higher soft error tolerant capability than the existing methods. For driving voltage VDD=3.3V, the proposed method is capable of masking transient pulses of magnitude 4.0V or less","PeriodicalId":113870,"journal":{"name":"2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122361597","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}

While an extensive literature exists on its mathematical characterization, little work has been reported on its possible technological basis. In this paper, a quantum-dot cellular automata (QCA) is investigated for testable implementations of reversible logic. Two new reversible gates (denoted as QCA1 and QCA2) are proposed. These gates are compared (in terms of delay, area and logic synthesis) with other reversible gates (such as Toffoli and Fredkin) for QCA implementation. As the bijective nature of reversibility makes testing significantly easier than in the general case, testing of the reversible gates is pursued in detail. C-testability of a 1D array is investigated for single cell fault as well multiple cell faults. Defect analysis of the reversible gates is pursued under a single missing/additional cell assumption","PeriodicalId":113870,"journal":{"name":"2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131997716","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}

Violante","doi":"10.1109/DFT.2006.49","DOIUrl":"https://doi.org/10.1109/DFT.2006.49","url":null,"abstract":"Processor cores embedded in systems-on-a-chip (SoCs) are often deployed in critical computations, and when affected by faults they may produce dramatic effects. When hardware hardening is not cost-effective, software implemented hardware fault tolerance (SIHFT) can be a solution to increase SoCs' dependability. However, SIHFT increases the time for running the hardened application, and the memory occupation. In this paper we propose a method that eliminates the memory overhead, using a new approach to instruction hardening and control flow checking during the execution of the application, without the need for introducing any change in its source code. The proposed method is also non-intrusive, since it does not require any modification in the main processor's architecture. The method is suitable for hardening SoCs against transient faults and also for detecting permanent faults","PeriodicalId":113870,"journal":{"name":"2006 21st IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121118484","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}
