In designs with high FPGA utilization, a sufficient number of routable fault-free elements may not be available for permanent fault repair. We present a new permanent fault repair scheme, in which the original design is reconfigured into another fault tolerant design that has smaller area, so the damaged element can be avoided. Three new schemes that fully utilize available fault-free area and provide low impact on availability are presented. Analytical results show that our schemes improve availability compared to a module removal approach. which removes a redundant module when it becomes faulty.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123764264","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}

It has been proposed to carry out such an analysis using fault injections in a hardware prototype of the circuit under design. This paper reports on a low cost environment using such a flow. A simple FPGA-based development board is used to emulate the circuit and the execution results are analysed on a PC computer. A generic, scalable, approach is proposed to overcome the limitations of such a simple set-up. Such an environment can for example allow a designer to perform efficient and low cost dependability analyses for IP blocks.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126654520","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}

To cope with the faults in each antecedent part, the degree in a candidate regarded as a faulty function is exchanged for one of the following: 0, the degree in the next function to the candidate, and the difference between the constant and the degree in the next function to the candidate. To cope with the faults in the consequent part, several fuzzy variables are shifted, and then the fuzzy inference is executed with the membership functions representing shifted variables. Experimental results for a commercial controller show that the influence of any single fault deviating the normal deterministic output of the controller is compensated completely.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124402122","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 monitor provides a solution to the problem of verifying the multiple power and ground connections, required to assure a proper power distribution to today's complex designs. These connections are very difficult to verify as they are connected in parallel and hence a failing connection will only marginally affect the overall connection characteristics but will affect a device's reliability. The application of the monitor described is an alternative and improvement to the currently used optical. X-ray and other inspection techniques. The monitor presented is designed such that it is fully transparent, testable, guarantees a proper detection, irrespective of local and global process parameter variations -avoiding the need for calibrationand can be put in a power down mode. The application of the monitor is based on the detection of a current flowing through the tested connection, thereby exploiting the inherent resistance of the connection. The sensor can easily be merged to different technologies without making major changes, which makes it well suited for intellectual property re-use.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"46 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114130596","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 technique requires the overlapping step response of the Circuit Under Test (CUT) for two circuit configurations. Each configuration can be realized by changing the topology of the CUT or by sampling two CUT nodes with differing step responses. The technique can effectively detect both soft and hard faults and does not require an analog-to-digital converter (ADC) and/or digital-to-analog converter ( DAC). It also does not require any precision voltage sources or comparators. The approach does not require any additional analog circuits to realize the test signal generator and a two input analog multiplexer for CUT test node sampling. The paper concludes with the application of the proposed approach to a circuit found in the work of Epstein et al.

A second approach is also proposed. this approach is based on adding a variable number of additional states to a cell with a known table. This approach requires at most (m+k+/spl alpha/)(n+k+/spl alpha/)( m/k+1)(n/k+1) tests, where m and n are the number of states in the two dimensions of signal flow, /spl alpha/=1(0) if (partial) fail observability is applicable to the state table and k is the variable number of additional states per direction (2/spl les/k/spl les/m.n).

It could detect random defects not caught by traditional \"stuck-at-fault\" functional testing. While effectiveness of traditional IDDQ test is severely affected by the large background current of deep submicron devices, several approaches have been raised on IDDQ-based methodologies to improve its fault detection sensitivity. This paper presents a new methodology based on one of the field approaches, while taking additional results of a specific test sub-circuit that monitored device speed performance into consideration. Dynamic variation due to process distribution is properly reflected via the test sub-circuit, which then leads to consistent fault detection criteria among all IDDQ measurement vectors.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"265 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123288394","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 probability of these faults has been estimated by means of Inductive Fault Analysis (IFA) and has been found to be, for the majority of cases, comparable if not one order of magnitude higher than that of other most likely microprocessor faults. The effects of the most likely clock faults has then been analyzed by means of electrical level simulations. Differently from what is generally implicitly assumed, we have found that only a small percentage of these faults results in a catastrophic failure of the microprocessor, thus being possibly easily detectable during manufacturing test, while the majority results in a local failure, which cannot be detected during manufacturing test, although compromising the microprocessor correct operation and causing an unacceptable decrease in its reliability.","PeriodicalId":187031,"journal":{"name":"Proceedings 2001 IEEE International Symposium on Defect and Fault Tolerance in VLSI Systems","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122592902","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}
