Abstract :
Safety critical systems need methods for chips to monitor their health in the field. This paper proposes to use the embedded SRAM as a monitor of system health. The bit failures are tracked and the cause of each bit failure is diagnosed with on-chip built-in self test (BIST). The wearout model parameters are estimated from the diagnosis results and combined with system wearout simulation data to estimate the remaining lifetime of a system.
