ABSTRACT
This work concerns metrics for evaluating microarchitectural enhancements to improve processor lifetime
reliability. The commonly used metric is mean time to failure (MTTF). However, MTTF does not provide
information on the reliability characteristics during the relatively short operational life of a processor. We
study nTTF, the time to failure of n% of the population. nTTF describes the failure process more accurately
