Cost considerations often do not permit over-designing the power supply infrastructure for test mode, considering the worst-case scenario. Test application must not over-exercise the power supply grids, lest the tests will damage the device or lead to false test failures. The problem of debugging a delay test failure can therefore be highly complex. We argue that false delay test failures can be avoided by generating \"safe\" patterns that are tolerant to on-chip variations. A statistical framework for power-safe pattern generation is proposed, which uses process variation information, power grid topology and regional constraints on switching activity. Experimental results are provided on benchmark circuits to demonstrate the effectiveness of the framework.","PeriodicalId":6403,"journal":{"name":"2007 IEEE International Test Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88579540","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 value of n is typically determined based on test set size constraints, and certain values have become standard. In this work we investigate appropriate values for n by considering the saturation of the n-detection test generation process. As n is increased, eventually the rate of increase in test set quality starts dropping. Saturation occurs when the increase in test set quality with n drops below a certain level. We introduce three parameters of an n-detection test set to measure saturation of the test generation process: (1) the fraction of faults detected n times or less by the test set, (2) the fraction of faults detected fewer than n times by the test set, and (3) the test set size relative to the size of a one-detection test set. We demonstrate that the behavior of each one of these parameters follows a unique pattern as n is increased, and certain features of this behavior can be used to identify saturation. All the parameters are easy to compute during the test generation process.","PeriodicalId":6403,"journal":{"name":"2007 IEEE International Test Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76747916","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 granularity of the partitioning was the key factor in achieving the results: a 33-element partition of the AMDtrade Athlon CPU chip resulted in better than a ~80% reduction in test time compared to aflat model of the entire chip.

This paper presents a fully digital-compatible built-in self-test strategy for ADC linearity testing using all digital testing environments. On-chip, low-accuracy DACs, which are area efficient and simple to design, are implemented as the stimulus generator. ADCs' nonlinearities are tested using a histogram-based method under the control of a logic block. The described strategy is capable of characterizing ADC transition levels one by one with small hardware overhead. Simulation and experimental results show that the proposed circuitry and BIST strategy can test the INLk error of 12-bit ADCs to plusmn0.2 LSB accuracy level using only 7-bit linear DACs.","PeriodicalId":6403,"journal":{"name":"2007 IEEE International Test Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74389359","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}

This technology allows for JTAG testing of partially or fully populated SiPs in wafer form, in advance of final packaging. The technology utilizes non-contact GHz short-range, near field communications to transfer bi-directional data to SiP substrates; creating a wireless test access port or WTAP. The system is integrated with a standard probe card to deliver power and wireless signals. The wireless probes convert high frequency RF (GHz) transceiver signals to standard tester ATE logic levels and allow the use of standard probers and JTAG testers. In addition, all transceivers (DUTand probe) use antenna structures and electronics that are fully CMOS compliant. Enhancing the economics of SiP manufacture by enabling parallel non-contact testing of SiPs before packaging is a key benefit of this technology.","PeriodicalId":6403,"journal":{"name":"2007 IEEE International Test Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81684030","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}

However, the most commonly studied defect models (the gate-delay and path-delay fault models) do not adequately capture the complex timing characteristics that a delay fault can exhibit. In this work, we present a novel diagnostic technique that is used to extract an accurate delay fault model we call a segment network fault without the need for any timing information. In our simulation-based experiments, we successfully diagnose delay faults of varying complexity demonstrating the usefulness of the new delay fault model for the purposes of delay defect characterization.","PeriodicalId":6403,"journal":{"name":"2007 IEEE International Test Conference","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89511243","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}
