Traditionally, noise analysis tools use the conservative assumption that all neighbors of a net can switch simultaneously, thereby producing the worst-case noise on a net. However, due to the logic correlations in the circuit, this worst-case noise may not be realizable, resulting in a so-called false noise failure. Since the problem has been shown to be NP-hard in general, exact solutions to this problem are not possible. In this paper, we therefore propose a new heuristic to eliminate false noise failures based on the resolution method. It is shown that multi-variable logic relations can be computed directly from a transistor level description. Based on these generated logic relations, a characteristic ROBDD for a signal net and its neighboring nets is constructed. This ROBDD is then used to determine the set of neighboring nets that result in the maximum realizable noise on the net. The proposed approach was implemented and tested on industrial circuits. The results demonstrate the effectiveness of the approach to eliminate false noise failures.","PeriodicalId":20510,"journal":{"name":"Proceedings International Symposium on Quality Electronic Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72635082","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}

These constraints make all-digital solutions (digital PLLs and DLLs) an attractive option (Dunning et al, 1995; Fried, 1996; Minami et al, 2000). This paper describes a digital delay-line architecture that can be used for these applications in a 0.11 /spl mu/m (silicon gate length) CMOS technology. Process variability and sensitivities increase at these geometries and it is difficult to meet target specifications across the entire spread of variations in process, voltages and temperatures (PVT corners).

This overhead includes the skew and the jitter of the clock. It also includes the setup time and the clock-to-output delay of the flip-flops. This paper discusses how much energy should be allocated for sequencing in these systems. It is pointed out that providing too little energy is just as bad as providing too much. It is also argued that directly trying to minimize the energy-delay product of the sequencing subsystem is practically not the right thing to do. A model for the relationship between supply voltage, clock frequency, and power dissipation is developed and empirically verified for a SPARC V9 microprocessor. An expression for the optimal energy allocation in a system is derived. Then, based on this optimum, a methodology to design energy-efficient systems is proposed.","PeriodicalId":20510,"journal":{"name":"Proceedings International Symposium on Quality Electronic Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83316063","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}

To suppress the leakage current in a standby mode, Boosted Gate MOS (BGMOS) is effective, which is based on cooperation between technology level and circuit level. To reduce the power in an active mode, V/sub DD/-hopping and V/sub TH/-hopping are promising, which are cooperative approaches between circuit and software. The power consumed in an interconnect system is another issue in low-voltage deep-submicron designs. A cooperative approach between VLSI and assembly to the interconnect power problem is also discussed.","PeriodicalId":20510,"journal":{"name":"Proceedings International Symposium on Quality Electronic Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83429529","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 space-sizing which allows the length to change gives more flexibility in solving practical problems. There are two major contributions of this paper. First, we prove that for general topology, a relaxed version of this problem is also convex. Second, we present the sequential network simplex algorithm which can solve those problems with extreme efficiency. Experimental results on several large scale problems, using a PC with a 500-MHZ Pentium III processor, show that our algorithm can solve problems with hundreds of thousands of variables within a few minutes and has a speed improvement of 25+ over sequential linear programming. Experimental results also show that about 50% of the power delivery area can be reduced using our algorithm.","PeriodicalId":20510,"journal":{"name":"Proceedings International Symposium on Quality Electronic Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84175917","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 first phase is a topological analysis used to screen non-critical network configurations, which does not require computationally expensive steps such as parasitic extraction and circuit-level simulation. The second phase is a detailed nominal skew computation based on accurate 3D extraction, performed on a small set of configurations identified as critical by the topological analysis. The third phase is a variational analysis of the impact of process variations and design parameters on the clock skew, that might induce timing margin violations.

The experimental research demonstrates that the quality of the new information-driven logic synthesis tools and the harmony of the new uniform approach results in much better circuits than the circuits from all other flows.

From the device integration point of view, the attainment of low extrinsic resistance, carrier transport in the double-gated thin silicon channel and threshold voltage control, remained significant obstacles to high-performance double-gate CMOS structures. We report how these issues were addressed to achieve world-record double-gate device performance. The second gate in a double-gate device can be utilized for low-power and mixed-signal applications. The flexibility of individually controlling the two gates provides opportunities for overall system performance improvement. Ultra-low voltage operation of double-gate CMOS inverters was demonstrated. Finally, we discuss the migration of existing circuit/layout designs to double-gate device technology.","PeriodicalId":20510,"journal":{"name":"Proceedings International Symposium on Quality Electronic Design","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2002-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76530859","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}
