Multiple scan chain test scheme provides very low scan power by skipping many long scan chain switching activities. Based on two-dimensional scan shift control, we can achieve low test power with simple and small overhead structure. The proposed scheme skips many unnecessary don't care (X) patterns to reduce the test data volume and test time. The experimental results of the proposed scheme illustrate the significant improvement in shift power reduction, test volume and test time reduction. Compared with traditional single scan chain design, the large benchmark b17 of ITC'99 has over 50% reduction in test data volume and over 40% reduction in test time with little area overhead and very few extra pins, and the power reduction is over 97%.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132380777","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}

Because this waiver information is not conveyed in any consistent manner with the IP, waived IP design rule violations that reappear when the IP is integrated into a full-chip design must typically be investigated as though they are new violations. This paper will review various historic methods used to identify waived errors at the chip level, then propose a new automated method for identifying and eliminating waived errors, allowing chip designers to achieve accurate design rule checking results while minimizing debug time.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122210492","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 costs additional power due to area over-dimensioning during synthesis. We present a new design strategy for digital CMOS IP that makes use of forward body biasing. Our approach renders consistently a better performance-per-area ratio by constraining circuit over-dimensioning without sacrificing circuit performance. Dynamic power is reduced depending upon the ratio of flip-flops to logic-gates, and data activity. On a set of benchmark circuits in 65nm LP-CMOS, we observed performance-per-area improvements up to 81%, area and leakage reductions up to 38%, and total power savings of up to 26% without performance penalties.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"28 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114127414","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 series of PCMO-based resistive switch devices (RSDs) with different geometry sizes were fabricated. Our E-test results show that by reducing the PCMO layer thickness from the normal value of about 200nm to 30nm, a low switching voltage (within ±2.5V) can be achieved. The reduction of PCMO layer thickness does not incur visible impact on device reliability: no significant degradation of two resistance states was observed after 1500 programming cycles. Based on the extrapolation from the measured electrical parameters of PCMO-based devices, we analyzed the design requirements of PCMO-based resistive memory with different cell structures in sub-100nm technologies. Our simulations show that one-transistor-one-RSD (1T1R) cell structure can be successfully scaled down to 22nm technology node. However, the scaling of one-non-ohmicdevice-one-RSD (1N1R) cell structure is significantly limited by the low driving ability of current non-ohmic device technology.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"106 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120932374","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 SRAM cell is subjected to a dual-VTh assignment based on a novel statistical Design of Experiments-Integer Linear Programming (DOE-ILP) approach. Experimental results show 44.2% power reduction (including leakage) and 43.9% increase in the read static noise margin compared to the baseline design. The process variation analysis of the optimized cell is carried out considering the variability effect in 12 device parameters. A 8 × 8 array is constructed to show the feasibility of the proposed SRAM cell.

The statistical gate delay models in being, most of which take the forms of low order polynomials, are suffering from either enormous characterization cost or poor accuracy. We propose in this paper a statistical comprehensive gate delay model including both the effects of process variation and operating conditions, i.e. input slope and output load. With the help of effective dimension reduction, we can use only a couple of random variables to present the effect of process variation, which enables a simple modeling methodology as well as a cheap characterization process. This model can be changed into the polynomial forms required in some block based SSTA or directly used in Monte Carlo based SSTA. The error of the model is shown well below 5% compared with golden Monte Carlo data.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123111616","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}

Improving the energy-efficiency and battery-lifetime of the monitoring units without sacrificing the acquired signal quality is a key challenge in large-scale deployment of bio-electronic systems for remote wireless monitoring. In this paper, we present a design methodology for low power wireless monitoring of Electroencephalography (EEG) data. The proposed design performs a real-time accuracy energy trade-off by controlling the volume of transmitted data based on the information content in the EEG signal. We consider the effect of different system parameters in order to design an optimal system. Our analysis shows that the proposed system design approach can provide significant savings in transmitter power with minimal impact on the monitored EEG signal accuracy. We analyze the impact of noise of the wireless channel and show that an adaptive compression system has better performance for BER ≪ 10−4.","PeriodicalId":369046,"journal":{"name":"2010 11th International Symposium on Quality Electronic Design (ISQED)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126860725","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}
