Coupled electro-thermal simulation can be used to assess the impact. Simulation, however, is time consuming. Furthermore, it does not give insight into the device's performance robustness against self-heating. We propose in this paper a novel metric, metric for electro-thermal sensitivity (METS), for characterizing a device's electrical robustness to self-heating. We demonstrate the effectiveness of METS in characterizing FinFETs, novel double-gate devices promising to replace traditional MOSFETs because of their reduced leakage currents. FinFETs are an ideal case study for METS as they have ultra thin bodies and are thus prone to self-heating. We show that our proposed metric, METS, is capable of characterizing the self-heating behavior of FinFETs in the on and off states","PeriodicalId":138839,"journal":{"name":"7th International Symposium on Quality Electronic Design (ISQED'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129178793","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}

Power islands: a high-level technique for counteracting leakage in deep sub-micron 动力岛:一种高级技术，用于抵消深亚微米的泄漏

In this work, we show experiments that illustrate the significant increase in the ratio of the leakage to the total power as the DSM process nodes shrink. We also present a high-level design/synthesis method, called power islands that minimize the leakage in the circuit by partitioning it into islands. Each island is a cluster of logic whose power can be controlled independent from the rest of the circuit, and hence can be completely powered down when all the logic contained within it is idling. The partitioning is done in such a way that the components with maximally overlapping lifetimes are placed on the same island. A main benefit of power islands is the elimination of leakage in inactive components during the power down cycles of the islands, and hence a decrease in circuit's power consumption. The effectiveness of the proposed technique is demonstrated through several examples implemented with 4 different feature sizes: 180 nm, 130 nm, 100 nm and 70 nm. These experiments showed improvements in leakage ranging from 41% to 80% at 70 nm due to power islands","PeriodicalId":138839,"journal":{"name":"7th International Symposium on Quality Electronic Design (ISQED'06)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134019094","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 CAD flow has been proposed based on the dual-Vt assignment algorithm and placement for realizing the dual-Vt FPGA architecture. Logic elements within the logic blocks are the candidates for dual-Vt assignment. We propose an architecture in which there are two kinds of logic blocks, one with all high-Vt logic elements and another with a fixed percentage of high-Vt logic elements. These two kinds of logic blocks are then placed in such a way that the FPGA architecture remains regular. Results indicate that in the ideal case of dual-Vt assignment, over 95% of the logic elements can be assigned high-Vt. Results show that leakage savings of 55% can be achieved. Design tradeoffs for various ratios of the two kinds of logic blocks are investigated.

For the first time, a fast and accurate methodology FASER based on static, vector-less analysis of error rates due to single event upsets in general combinational circuits is proposed. Accurate models are based on STA-like pre-characterization methods, and logical masking is computed via binary decision diagrams with circuit partitioning. Experimental results indicate that FASER achieves good accuracy compared to the SPICE-based simulation method. The average error across the benchmark circuits is 12% at over 90,000X speed-up. The accuracy can be further improved by more accurate cell library characterization. The run-time for ISCAS '85 benchmark circuits ranges from 10 to 120 minutes.

The bit sequences of multiple cells of an LFSR, which is used as test pattern generator, are exploited for effectively encoding the test set of the core under test (multiphase architecture). A new algorithm which comprises four heuristic criteria is introduced for efficiently selecting the required seeds and LFSR cells. Also, a cost metric for assessing the quality of the algorithm's results is proposed. By using this metric, the process of determining proper values for the algorithm's input parameters is significantly simplified.

One of the most critical issues in the context of SPMs is to select the data elements to place in them since the gap between SPM access latencies and off-chip memory access latencies keep increasing dramatically. Previous research considered this problem and attacked it using both static and dynamic schemes. Most of the prior efforts on data SPMs have mainly focused on single application scenarios, i.e., the SPM space available is assumed to be managed by a single application at any given time. While this assumption makes sense in certain domains, there also exist many cases where multiple applications need to share the same SPM space. This paper focuses on such a multi-application scenario and proposes a nonuniform SPM space partitioning and management across concurrently-executing applications. In our approach, the amount of data to be allocated to each application is decided based on the data reuse each application exhibits","PeriodicalId":138839,"journal":{"name":"7th International Symposium on Quality Electronic Design (ISQED'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124935884","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}

Statistical design methods can provide a realistic assessment of design space, and improve the design quality by exploiting its stochastic behavior. We present a novel probabilistic time budgeting algorithm that translates the application expected delay constraint into its components delay constraints. Our algorithm which is based on mathematical properties of the problem, determines the optimal maximum weighted timing relaxation of an application under expected delay constraint.
