However in recent years, an increasing interest has been drawn to the problem of radiation-induced temporary faults, also called soft errors, which corrupt memory content even during the normal functioning of a system. In this paper, a mitigation technique for the protection of critical data in electronic devices from transient errors that manifest themselves as bit-flips in memory is proposed. In order to cope with this problem we take advantage of convolutional codes and we introduce two architectures to protect memory content with little area and performance overheads. A coding-decoding scheme implemented using sequential logic. The encoding is performed as in classical convolutional encoding, processing the input stream with a shift-register based architecture. The decoder, however, differs from classical decoding schemes in terms of complexity.","PeriodicalId":334529,"journal":{"name":"2008 13th European Test Symposium","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129592940","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 application of test algorithms for SRAM memories to cache memories thus requires opportune transformations. In this paper we present a procedure to adapt traditional march tests to testing the data and the directory array of k-way set-associative cache memories with LRU replacement. The basic idea is to translate each march test operation into an equivalent sequence of cache operations able to reproduce the desired marching sequence into the data and the directory array of the cache.","PeriodicalId":334529,"journal":{"name":"2008 13th European Test Symposium","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125998818","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 key defining characteristic of frequency modulated systems is the constant amplitude of the transmitted signal making it impossible to use envelope-based built-in test (BIT) techniques. In this paper, an efficient BIT technique for such transmitters using lowpass filters is proposed. The proposed BIT technique is low-cost and has minimal impact on RF transmitter performance. It can also be used to efficiently test devices such as voltage-controlled oscillators (VCOs), phase locked loops (PLL) etc through frequency discrimination. Simulation results and hardware measurements demonstrate the feasibility of the proposed approach.","PeriodicalId":334529,"journal":{"name":"2008 13th European Test Symposium","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129778827","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}

Although point techniques are available for reducing capture IR-drop, there is a lack of complete capture-safe test generation flows. The paper addresses this problem by proposing a novel and practical capture-safe test generation scheme, featuring (1) reliable capture-safety checking and (2) effective capture-safety improvement by combining X-bit identification & X-filling with low launch- switching-activity test generation. This scheme is compatible with existing ATPG flows, and achieves capture-safety with no changes in the circuit-under-test or the clocking scheme.","PeriodicalId":334529,"journal":{"name":"2008 13th European Test Symposium","volume":"57 15","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-05-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113943166","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}
