Abstract
Embodiments include methods, and systems of an integrated circuit having electromigration wearout detection circuits. Integrated circuit may include a detection element and a reference element. Detection element is subject to normal operation current. Reference element is not subject to normal operation current. A resistance of detection element is monitored to detect electromigration wearout. The electromigration wearout detection monitoring circuit may be configured to perform: periodically measuring resistance of detection element, calculating resistance change of detection element over a predetermined time period, comparing resistance change of detection element calculated to a predetermined safety threshold, and take mitigation actions when resistance change of detection element exceeds predetermined safety threshold. The mitigation actions may include switching to a redundant circuit of the integrated circuit, shutting down the integrated circuit, and sending a signal to initiate a service call. The predetermined safety threshold may be 1% of resistance change of the detection element.
