The slowdown in process scaling due to fundamental limitations of transistors and copper wires, has put tremendous challenges on traditional integrated system design methodology and continued performance improvements. These fundamental component limitations (sub-threshold transistor leakage and wire capacitance/resistivity) have brought into the focus the need for energy-efficient cross-cut integrated system design, and the need to accelerate the adoption of promising emerging technologies that overcome these limitations.

This talk illustrates several examples of our cross-cut design methodology, which encompasses cross-layer modeling that connects process, device and circuit optimizations to system-level metrics, as well as design of early characterization platforms to accelerate adoption and provide feedback to modeling and device design. These examples focus on development of integrated information transfer systems (e.g. many core processor and memory systems, and network communication infrastructure), with scaled electronics, as well as emerging mechanical and photonic devices.

The key observations are that cross-layer modeling and design approach coupled with design of early characterization platforms, set-up the rightpathway for development at all layers of design hierarchy (from devices to architecture level) and significantly accelerate the adoption of promisingnew technologies. Based on these design principles, we project that in thenext decade tailored hybrid (electrical/optical and mechanical) integrated systems will provide orders of magnitude performance improvements at the system level.

Speaker Biography

Vladimir Stojanovic is the Emanuel E. Landsman Associate Professor of Electrical Engineering and Computer Science at MIT. His research interests include design, modeling and optimization of integrated systems, from CMOS-based VLSI blocks and interfaces to system design with emerging devices like NEM relays and silicon-photonics. He is also interested in design and implementation of energy-efficient electrical and optical networks, and digital communication techniques in high-speed interfaces and high-speed mixed-signal IC design.

Vladimir received his Ph.D. in Electrical Engineering from Stanford University in 2005, and the Dipl. Ing. degree from the University of Belgrade, Serbia in 1998. He was also with Rambus, Inc., Los Altos, CA, from 2001 through 2004. He received the 2006 IBM Faculty Partnership Award, and the 2009 NSF CAREER Award as well as the 2008 ICCAD William J. McCalla, 2008 IEEE Transactions on Advanced Packaging, and 2010 ISSCC Jack Raper best paper awards.
