Due to increasing background currents, however, also these methods are beginning to have problems to distinguish between good and bad devices. A good evaluation algorithm for IDDQ takes all known information about 'good' and 'bad' parts into account, i.e. it 'knows' how the IDDQ signatures of good and bad parts look like. Unfortunately, not only do the signatures of good parts differ significantly, but the signatures of bad parts differ even more. Moreover, since IDDQ faults are more often than not non-fatal (not impairing the functionality), it is frequently hard to say if a device is really 'good' or bad'. There are two kinds of information, however, which are known without referring to a certain process or IC type: one is the model of the IDDQ fault, and the other is the statistical distribution of the background-IDDQ. Using this information, an estimator with higher discrimination capability than the traditional Delta-IDDQ-approach is created. Measurement results form several lots of a 180 nm chip are presented..","PeriodicalId":297689,"journal":{"name":"2008 11th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117276868","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}

Sophisticated methods for each sub-task were and are still developed, but rarely a complete solution is proposed on circuit level. This paper fills the gap by proposing a concept that combines all required steps to implement fault tolerant digital circuits. The approach is based on asynchronous Four-State Logic (FSL) logic, which belongs to the family of Quasi Delay Insensitive (QDI) circuits. Contrary to conventional approaches, using synchronous logic plus additional hardware and/or software to achieve fault tolerance, we use the inherent properties of FSL for fault detection, fault localization and fault recovery. Only deadlock detection and error mitigation require an enhancement of the conventional FSL (four state logic) design. For this purpose, a monitoring unit has to be added and self-healing cells were developed that can be handled as conventional logic within the design flow. The feasibility of the approach is verified by a first prototype implementation of a fault tolerant adder circuit.","PeriodicalId":297689,"journal":{"name":"2008 11th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124804655","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}

Usage of primitive polynomial with a small number of feedbacks is considered a classical rule of thumb that is usually implemented. Although being beneficial for very long test sequences, primitive polynomial cannot guarantee fast fault coverage growth, which is a critical issue in pseudo-random-pattern-generator-based embedded test approaches. Hence, selecting a good initial state would be the main instrument for getting the fast coverage gain. In this work, we propose a formal analytical method to calculate a customized polynomial and seed pair for each separate design/test case. This novel technique allows shortening BIST runtimes and increasing fault coverage by embedding given efficient test patterns into the LFSR sequence. Being used in mixed-mode BIST techniques, the method shows decreasing trend in test application time and/or necessary test pattern storage resources. Our comparison against primitive polynomial based sequences support these observations.","PeriodicalId":297689,"journal":{"name":"2008 11th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115835651","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 contrast to the digital domain, manual tasks are often dominant in today's analog design flows, due to the higher complexity of constraints, influencing a circuits behaviour. In the area of physical design, routing significantly contributes to the overall design complexity. In this paper we present a novel approach to corner stitching based data structures for routing applications. Due to their trapezoidal shape, layout elements with arbitrary angles can be directly represented. Our work mainly strives for new routing methodologies in analog circuit design aiming at the improvement of routing result quality. To overcome common problems concerning the design of corner stitching data structures we employ a new software tool for visualization and manipulation.","PeriodicalId":297689,"journal":{"name":"2008 11th IEEE Workshop on Design and Diagnostics of Electronic Circuits and Systems","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116038830","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}
