Dr. Sani Nassif is Manager of the Tools and Technology Department at IBM Austin Research Laboratory, where he is presently managing the tools and technology department, which is focused on design/technology coupling. Dr. Nassif has a long standing collaboration with our research group. In the context of this project he will help the research team in defining the requirements for delay models and timing analysis techniques necessary to capture the variability effects relevant in the latest IC technologies, particularly de 22nm technology node. Dr. Howard Chen is a Research Staff Member at the Design Automation Department of the IBM Thomas J. Watson Research Center. Dr. Chen is a recognized international expert in power analysis and estimation for the latest IC technologies. In the context of this project he will help the research team in identifying the relevant variational effects that need to be captured for accurate power modeling and analysis.
