Research
Openings: I currently have a couple
of openings for Ph.D. graduate students (only) who have the
background in both IC design and nanoscale silicon technology. If you are
interested, welcome to come by during my office hours. For more in-depth
information, please visit the webpage of
the NIMO Group.
My research focuses on modeling and design techniques for reliable,
low-power, and high-performance systems, motivated by both evolutionary and
revolutionary advances in nanoscale technology. I am particularly interested
in the following topics:
 Compact modeling for nanoscale CMOS and
post-silicon technologies
Physical-level design and tools for
variability and reliability
Reliable integration of emerging technologies
High-speed
and low-power design techniques
To explore early stage design solutions,
Predictive Technology Model (PTM) is developed for sub-45nm technology
generations, covering traditional bulk CMOS, alternative materials and structures (e.g., FinFET), and
post-silicon devices (e.g., CNT-FET). In addition, this predictive modeling
framework accurately captures emerging physical effects, such as variability and reliability. To investigate more,
welcome to visit
PTM and send me your valuable feedbacks.
