System monitoring

°Voltages monitoring

°Temperature monitoring

°Clock frequency monitoring

Error management

°Error management is handled and implemented within the PMU

°Errors are signaled as interrupts and mirrored to PL

°All hardware and software errors captured in ERROR_STATUS_1

°ERROR_STATUS_2 registers are visible to the PMU, RPU, APU, and PL

Monitoring of activation of common cause failures (CCF) by PMU

°MBIST, SCAN, reset, power control

Hang protection

°Cleanup of outstanding transactions under partial reset

Meta-stability errors

°PS uses redundant flip-flops in selected clock crossings

Aging errors

°Large on-chip variation (OCV) margin to account for aging effects
