The recent popularity of 3D IC technology stems from its enhanced performance capabilities and reduced wirelength. However, wire congestion and thermal issues are exacerbated due to the compact nature of these layered technologies. In this paper, we develop techniques to reduce the maximum temperature and wire congestion of 3D circuits without compromising(More)
In this paper, we propose a new technique to accurately decompose process variation into two different components: (1) spatially correlated variation, and (2) uncorrelated random variation. Such variation decomposition is important to identify systematic variation patterns at wafer and/or chip level for process modeling, control and diagnosis. We(More)
Artificial neural networks offer an attractive paradigm for the design of behavior and control systems in robots and autonomous agents for a variety of reasons, including: ability to adapt and learn, potential for resistance to noise, faults and component failures , potential for real-time performance in dynamic environments (through massive parallelism and(More)
The Sarbanes-Oxley (SOX) Act of 2002 is one of the, if not the, most important pieces of legislation affecting corporations traded on the U.S. stock exchanges. While SOX does not explicitly address the issue of information security, the definition of internal control provided by the SEC, combined with the fact that the reporting systems in all firms(More)
—In this paper, we propose a new technique to achieve accurate decomposition of process variation by efficiently performing spatial pattern analysis. We demonstrate that the spatially correlated systematic variation can be accurately represented by the linear combination of a small number of templates. Based on this observation, an efficient sparse(More)
We trace the evolution of the auto component supply chain in India (following the opening of the Indian economy in 1990) using a combination of data on firm and sectoral performance, customer satisfaction surveys and interviews with experts. During the last decade, the industry has made remarkable progress on multiple fronts. This is particularly true with(More)
Delay and power minimization are two important objectives in the current circuit designs. Retiming is a very effective way for delay optimization for sequential circuits. In this paper we propose a framework for multi-level global placement with retiming, targeting simultaneous delay and power optimization. We propose GEO-P for power optimization and GEO-PD(More)
