9th Annual Austin CAS Conference 2008 On Friday, February 22, 2008, the IBM Austin Center for Advanced Studies (Austin CAS) held a successful 9th Annual Austin CAS Conference. Sani Nassif, Manager, Tools & Technology for the IBM Austin Research Laboratory, conducted the kickoff with approximately 50 attendees from STG business units, as well as an exceeding level of University participation, including a first time attendance and collaboration by Texas State University. Professor Lizy John from the University of Texas at Austin delivered an inspiring Keynote on "Performance and Power Modeling: The Return of Synthetic Benchmarks". Divisions around the IBM Austin campus enjoyed hearing innovative presentations on key research technologies by professors and graduate students. Our research environment is dedicated to promoting and cultivating relationships between IBM and major universities across the US. As a result, the collaborative efforts of our internal business units and the academic world continues to embody the very principles of our research environment...moving new ideas, new approaches to the highest levels. The strength of this event is derived from the innovativeness of the research being conducted....all with a demonstrated level of aggressiveness, thoughtfulness and the students seem to have boundless energy and passion for what they are working on. We list below the Final Program that was presented during this non-IBM-Confidential conference. For more information, please contact Heather Wagner, or Christa Mace.   ********************************************* Final Program Friday, February 22, 2008 10:00am Breakfast & Registration 10:20am Welcome and Opening Remarks Kevin Nowka, Senior Manager, VLSI Systems, IBM Austin Research Laboratory 10:30am Session 1: Technology and Circuit Variability Issues Session Chair: Sani Nassif On-chip Negative Bias Temperature Instability Sensor using Slew Rate Monitoring Circuitry Amlan Ghosh, Ching-Te Chuang, and Richard B.
