Fast/sub 14/ Technology derives its name from the atomic number of silicon (which translates to \"Fast Silicon Technology\"). Fast/sub 14/ Technology is comprised of five critical design elements: Multiphase Overlapped Clocking; 1-of-N Dynamic Logic (NDO family); Expert Routing Technology/sup TM/; Unified Design Database; Design Methodology and Electronic Design Automation (EDA) Tools Suite. Fast/sub 14/ Technology enables a significant improvement in chip design productivity for high-speed digital logic. Fast/sub 14/ Technology also provides significant power and silicon area efficiency benefits over other design methodologies in the high-performance logic design space. These benefits enable embedded processors and special-purpose digital logic products to achieve the levels of performance previously achieved only through custom design flows while maintaining efficient levels of power. These high performance levels are achieved at greatly reduced development costs and with lower risk of circuit problems as compared to the custom design flows used for desktop processors.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

This consists in a progressive growth of the BD spot, and as a consequence, of the gate leakage, in times that under operation conditions can be a large fraction of the time required for circuit failure. The I-V characteristics of the BD spot under progressive BD are investigated and modeled in the relevant range of voltages. The model is based on an assumption concerning the physical structure of the BD spot. This is compared to direct TEM observations. Experimental conditions in terms of voltages and geometry leading to BD runaway, i.e., the transition from progressive to very fast BD transient are shown and discussed. Moreover, the impact on the BD transient of a different material for the gate electrode is studied in the case of tungsten, used in place of the standard poly-Si.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.

Model projections were compared with measured FMAX data for a 0.25/spl mu/m microprocessor. In this paper, an additional comparison is performed with a 0.13/spl mu/m microprocessor, illustrating the close agreement between the simulated and measured distributions in mean, variance, and shape for different values of temperature and supply voltage. The previous model revealed that within-die variations primarily reduce the mean FMAX, or reciprocally, increase the mean of the maximum critical path delay (T/sub cp,max/) distribution. In this paper, a closed-form analytical equation of the T/sub cp,max/ mean increase is derived as an extension to the FMAX distribution model, which further elucidates the dependency on within-die variations. For a given set of process- and circuit-level parameters, this model provides insight into the delay guard-band required to achieve specific performance goals. Moreover, the model identifies the point of diminishing returns for redesigning critical paths in the tail of the timing histogram. To explore the region of validity, a model assumption for the shape of the critical path delay distribution is examined to guide practical VLSI design decisions.","PeriodicalId":158994,"journal":{"name":"2004 International Conference on Integrated Circuit Design and Technology (IEEE Cat.
