It is composed of an N-stage main ring (arbitrary N larger than 3) and k-stage sub-feedback loops, where k is not the common divisor of N, N output phases can be obtained. With a linear model analysis, it comes to a result that oscillating frequency is related to k, and the phase difference between adjacent stages. With smaller k, higher oscillating frequency can be achieved.","PeriodicalId":6325,"journal":{"name":"2009 12th International Symposium on Design and Diagnostics of Electronic Circuits & Systems","volume":"76 1","pages":"28-29"},"PeriodicalIF":0.0,"publicationDate":"2009-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72637495","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 this context, manufacturers must develop methods and design solutions to improve reliability especially for automotive applications. For this purpose, ECC and BISR are probably the most efficient concepts to enhance memory reliability. However, such techniques are limited to correct errors occurring punctually within a word whereas in memories the stress of peripheral circuit can lead to an entire faulty bit or word line. This phenomenon is referred as Clustering Effect. This work proposes an on-line testing structure for clustering effects according to the word line plan. This test structure allows achieving a test time acceptable and is shown as low cost in term of surface overhead (3 HV transistors, 1 XOR, 1 MUX and 1 DFF). Adding our solution to recent ECC and BISR techniques, spatial or automotive applications could be easily targeted.","PeriodicalId":6325,"journal":{"name":"2009 12th International Symposium on Design and Diagnostics of Electronic Circuits & Systems","volume":"19 1","pages":"120-123"},"PeriodicalIF":0.0,"publicationDate":"2009-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82543771","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}

A weakness of this approach, however, is the potential for common cause faults: Faults affecting both cores in the same way will escape detection. Shared resources and signals are especially prone to such effects. In practice the efforts for providing a redundant power source are often prohibitive, thus rendering the power supply such a shared resource. While a complete failure of the supply voltage can be relatively easily accommodated in a fail safe system, short pulses can have subtle consequences and are therefore much more dangerous. In this paper we will perform an experimental study of the potential of such power supply induced faults to create common cause effects. For this purpose we first study their effects on the operation of a processor core. In particular we will show that, when applied with the most adverse parameters, they tend to cause timing violations in the critical path. In two instances of the same core there is therefore a non-negligible risk of common cause effects. We will quantitatively assess this risk through fault injection experiments into an FPGA based dual core design.","PeriodicalId":6325,"journal":{"name":"2009 12th International Symposium on Design and Diagnostics of Electronic Circuits & Systems","volume":"31 1","pages":"152-157"},"PeriodicalIF":0.0,"publicationDate":"2009-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82346232","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}

We approach this challenge with a self-timed thermal monitoring method which is based on the use of thermal sensors. Since leakage currents are sensitive to temperature and increase with scaling, we propose the use of a leakage current based thermal sensing for monitoring purposes. In this work we have implemented a novel thermal sensing circuit in 65nm CMOS technology, which converts analog temperature information into digital form. We have also proposed a novel thermal sensing and monitoring interconnection network structure based on self-timed signaling, comprising of an encoder/transmitter and decoder/ receiver. We have performed power supply noise, additive noise on sensor input signal and dynamic power supply voltage variation analysis on the thermal sensing circuit and show that it is robust enough under different operating temperatures.","PeriodicalId":6325,"journal":{"name":"2009 12th International Symposium on Design and Diagnostics of Electronic Circuits & Systems","volume":"39 1","pages":"246-251"},"PeriodicalIF":0.0,"publicationDate":"2009-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85879921","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}
