Abstract
Process variation is an increasingly important problem in
semiconductor devices as dimensions are scaled. New
architectures and design methodologies are required to
address these variations without incurring significant
performance or power degradation. Communication devices are
ideal candidates in which to explore the effects of process
variation because robustness to noise is already included
in their design paradigm. The challenge is to develop
architectures that express process variation as simply
another type of noise. We propose a three-tiered approach
to develop architectures that achieve this "process
variation scalability". An existing design exploration
framework for power/performance tradeoffs in communication
components can be extended to include these new robustness
tradeoffs. This research will serve as a launching pad to
enable exploration of much broader classes of robust
computational systems.
