High Performance Computing for Integrated Circuit Design

Over the last several decades, the impact of the rapid growth in integrated circuits processor capability on our daily and professional lives has been clearly evident. Technologies ranging from very high-performance research and applications including computers, smart phone, multimedia, entertainment devices, and personal digital assistants all benefit from this unprecedented growth. However, the rapid progress towards further miniaturization of the microelectronic components has revealed a number of difficult challenges in terms of materials, architectures, fabrication, and integration of nanoscale active and passive elements. These challenges threaten to impede the further improvements of IC microprocessor performance in the near future. Consider, for example, interconnects which are wiring systems that distribute clock, power, and input/output signals among the various circuits/systems functioning on a chip. Since the resistance and surface scattering effects increase as the feature size decreases, the interconnect RC delay, which determines the speed at which signals transfer between transistors, is now so high that the latency of communication in high-end processors are limited by the interconnect delay rather than the switching delay of the transistors. The down scaling of current technologies will cause RC delay to be at least five times larger by the year 2022 thereby negatively affecting performance of future electronic devices. Some of these issues are due to nanoscale quantum effects and need to be taken into account for design of future chips. In order to address such issues, computational approach based on multiscale methods, high performance computations, as well as close collaboration between academia and industry are needed. This talk addresses challenges and opportunities in high performance computing for integrated circuit design and gives an overview of possible research topics for industry and academia collaboration using high performance computing.


Saroj Nayak is a professor in physics, astronomy and applied physics at Rensselaer and is the director for NY State Focus Center at Rensselaer. Before joining the faculty at Rensselaer in 2000 Dr. Nayak was a Princeton Materials Institute Jr. Fellow at Princeton University. His research interests lie at the interface of physics, chemistry and engineering, with principle areas of focus on the study of atomic and electronic structures of matters using ab initio electronic structure calculation methods with large scale quantum molecular dynamics simulations.

Dr. Rasit Onur Topaloglu received his B.S. degree with High Honors in Electrical and Electronic Engineering from Bogazici University in Turkey. He received his M.S. degree in Computer Science and Ph.D. degree in Computer Engineering from University of California at San Diego. Since 2005, he has been with Advanced Micro Devices and later on with GLOBALFOUNDRIES, which is an advanced semiconductor manufacturer with technology coverage down to 28 nm and research down to 14 nm. Dr. Topaloglu’s research interests are VLSI systems and technology. He has over 40 international and refereed publications, four book chapters and an edited book, three granted and four pending patents, and a best paper award at IEEE International Symposium on Quality Electronic Design. He has chaired DAC Workshop on Parallel Algorithms, Programming, and Architectures (PAPA) in 2011. He serves in technical program committees for DAC and International Symposium on Physical Design. He serves as Semiconductor Research Corporation Science Area Coordinator for Computer Aided Design and Test as well as Circuits and Systems for GLOBALFOUNDRIES. He is also a Semiconductor Research Corporation Focus Center Research Program Associate for Concurrent Systems.
