Abstract: Aspects of the present disclosure provide techniques for predicting a failure of an integrated circuit, which may include receiving first aging sensor data during an idle state of the integrated circuit; determining a voltage compensation value based on the first aging sensor data; comparing a new voltage value based on the voltage compensation value to a threshold operating voltage; determining the new operating voltage value exceeds the threshold operating voltage; determining a warning state for the integrated circuit; receiving second aging sensor data during the idle state of the integrated circuit; receiving stored aging sensor data from an aging sensor data repository; comparing the second aging sensor data to the stored aging sensor data; determining that the second aging sensor data is inconsistent with the stored aging sensor data; and determining a danger state for the integrated circuit.

Abstract: Aspects of the disclosure are directed to sensing integrated circuit (IC) Back End Of Line (BEOL) process corners. In one aspect, an apparatus for sensing IC BEOL process corners includes a ring oscillator including a plurality of ring oscillator stages configured to generate an output waveform with a frequency state; and a shield net circuit including a plurality of shield net stages corresponding to the plurality of ring oscillator stages, the shield net circuit having a toggle input. And, a method includes generating an output waveform with a frequency state using a ring oscillator that includes a plurality of ring oscillator stages; modifying a plurality of ring oscillator stage time delays through a coupling between a plurality of shield net stages and the plurality of ring oscillator stages; and selecting the frequency state using a toggle input of a shield net circuit which includes the plurality of shield net stages.
