Information pertaining to real-time sensor-based violations occurring during field operation of a failing
integrated circuit component is used in conjunction with transition
delay automatic test pattern generation (ATPG) test result information to diagnose the failing
integrated circuit component. Real-time sensor-based violations can be captured during field operation at the
integrated circuit component, with a sensor-based violation indicating that a sensor value generated by a sensor of the integrated circuit (such as a path margin monitor, temperature monitor, or
voltage droop monitor) exceeds a sensor threshold value. Diagnosis of a failing integrated circuit component using real-time sensor-based violation information and transition
delay ATPG test result information can aid in identifying a culprit path in the integrated circuit component that is likely responsible for causing the integrated circuit component failure.
