Gupta","doi":"10.1109/TEST.2010.5699209","DOIUrl":"https://doi.org/10.1109/TEST.2010.5699209","url":null,"abstract":"The performance benefits of latch-based circuits have been known for some time. These benefits are due to the timing flexibility and skew-tolerance enabled by the ability of combinational logic blocks to borrow time from each other across the intervening level-sensitive latches. It has also been known that, by accommodating higher levels of process variations and small delay-defects, time borrowing can enhance yield at high clock frequencies. The main roadblock was that conventional scan-based delay testing approaches cannot be adapted from flip-flop-based (FF-based) circuits to latch-based circuits in a manner that can harvest above benefits. Recently, a scan-based delay testing approach has been proposed for latch-based circuits which holds the promise of harvesting the abovementioned performance and yield benefits. In this paper, we investigate two main questions. First, can this new scan-based delay testing approach provide high coverage of delay faults for all latch-based circuits- independent of the pervasiveness of time borrowing? Second, how do we design the circuit and develop tests so as to harvest maximal performance and yield benefits? We prove that the above delay testing approach for latch-based circuits obtains the maximum path delay fault coverage possible for any scan-based test methodology and this test quality is always greater than (or equal to) that obtainable for the corresponding FF-based circuit. We derive the conditions to satisfy during design and test development to guarantee maximal performance and yield benefits of latch-based designs vs. their FF-based counterparts. Hence, we show for the first time that it is possible for latch-based circuits to provide higher performance and yield and also to certify the higher performance via high delay test quality.","PeriodicalId":265156,"journal":{"name":"2010 IEEE International Test Conference","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130362682","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}

As frequencies increase above 500 MHz, jitter and duty cycle error become significant and more likely to affect logic function. Measuring these parameters off-chip can be too expensive or impractical. This paper describes how a PLL BIST is being implemented in production ICs to test jitter, duty cycle, phase delay, frequency ratio, and lock time. It discusses some of the implementation problems and lessons, and how characterization was performed using a PC with graphical test generation software and off-the-shelf reference clock sources to produce production test patterns. Results for a test chip are included, demonstrating that calibrated, picosecond-precision measurements are now practical for production test.","PeriodicalId":265156,"journal":{"name":"2010 IEEE International Test Conference","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130964966","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 achieved a linearity error of 4.2ps pp without calibration. The timing vernier occupies an area of 0.042mm2 and dissipates a power of 16mW from a 1.8V supply at an operating frequency of 373MHz.

In this paper, we first categorize the subthreshold-SRAM designs into three types, study the faulty behavior of different open defects for each type of designs, and then identify the faults which may or may not be covered by a traditional SRAM test method. For those hard-to-detect faults, we will further discuss the corresponding test method according to different each type of subthreshold-SRAM designs.

The ability of the receiver to correctly place a receive strobe within the data valid region of a bit fundamentally determines the bit error rate performance for a design or a particular device. The device must meet its performance requirements in the presence of non-ideal timing.

The cost of wafer manufacturing being fairly constant, product yield is one of the most significant variables for profitability. With the yield paretos increasingly dominated by systematic defects, yield learning based on product test is fast becoming a fundamental requirement. For an integrated device manufacturer like IBM, product-based yield learning is even more critical as this drives technology learning as well. In this paper, we will present some of IBM's yield learning techniques and several case studies from high-volume manufacturing. These techniques extend from test data analysis, to analysis of scan-based product diagnosis results, to detailed layout analysis in conjunction with test, diagnosis and inline defect inspection data. We will discuss the increasing levels of complexity associated with the various techniques and argue that an effective yield learning strategy must comprise all of the above.","PeriodicalId":265156,"journal":{"name":"2010 IEEE International Test Conference","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131370930","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}
