ICCAD is a premier and one of the most selective conferences devoted to technical innovations in design automation.

Hu won the award for paper, “Gate Sizing and Device Technology Selection Algorithms for High Performance Industrial Designs.”

Hu, in collaboration with Dr. Mustafa Ozdal and Dr. Steven Burns at Intel's Strategic CAD Laboratories, said it is becoming more important to create high performance designs with as low power as possible. To this end, they study the gate sizing and device technology selection problem for today’s industrial designs. They propose a Lagrangian Relaxation (LR) based formulation that decouples timing analysis from optimization without resulting in loss of accuracy, and a graph model that accurately captures discrete cell type characteristics based on library data.

The Lagrangian subproblem is modeled as a graph problem, with proposed algorithms to solve it. In the experiments, the importance of using the signoff timing engine to guide the optimization was demonstrated and the benefit of the graph model proposed to solve the discrete optimization problem was shown. Compared to a state-of-the art industrial optimization flow, their algorithms can obtain up to 38 percent leakage power reductions and better overall timing for real high-performance microprocessor blocks. Hu spent his faculty development leave at the Intel Strategic CAD Laboratories during the fall of 2010 with Ozdal and Burns in the working on this research.

Hu received the B.S. degree in optical engineering from Zhejiang University (China) in 1990, the M.S. degree in physics in 1997 and the Ph.D. degree in electrical engineering from the University of Minnesota in 2001. He worked with IBM Microelectronics from January 2001 to June 2002.

In 2002 Hu joined the electrical engineering faculty at Texas A&M. His research interest is in Computer-Aided Design for VLSI circuits, especially on large scale circuit optimization, clock network synthesis, robust design and on-chip communication. Honors include receiving a best paper award at the ACM/IEEE Design Automation Conference in 2001 and an IBM Invention Achievement Award in 2003. He has served as technical program committee members for DAC, ICCAD, ISPD, ISQED, ICCD, DATE and ISCAS. He is the technical program chair for the 2011 ACM International Symposium on Physical Design. Currently, he is an associate editor of IEEE Transactions on CAD and the ACM Transactions on Design Automation of Electronic Systems
