ABSTRACT
The progressive trend of fabrication technologies towards
the nanometer regime has created a number of new physi-
cal design challenges for computer architects. Design com-
plexity, uncertainty in environmental and fabrication con-
ditions, and single-event upsets all conspire to compromise
system correctness and reliability. Recently, researchers
have begun to advocate a new design strategy called Bet-
ter Than Worst-Case design that couples a complex core
component with a simple reliable checker mechanism. By
delegating the responsibility for correctness and reliability
of the design to the checker, it becomes possible to build
provably correct designs that effectively address the chal-
lenges of deep submicron design. In this paper, we present
the concepts of Better Than Worst-Case design and high-
