A fault-tolerant approach to microprocessor design, developed at
the University of Michigan, is presented. Our approach is based
on the use of in-situ checker components that validate the
functional and electrical characteristics of complex
microprocessor designs. Two design techniques are highlighted
a low-cost double-sampling latch design capable of eliminating
power-hungry voltage margins, and a formally verifiable checker
co-processor that validates all computation produced by a
complex microprocessor core. By adopting a "better than worst-
case" approach to system design, it is possible to address
