1. An on-chip sensor system, comprising:

  • an integrated circuit chip comprising a plurality of sensor groups located on respective functional blocks of the integrated circuit chip, wherein output of the sensor groups correlates to actual wear of the integrated circuit chip based on an actual operational environment of the integrated circuit chip, the plurality of sensor groups including;

    a first sensor group on a first functional block of the integrated circuit chip comprising first sensor structures that are configured to detect a measure of different amounts of wear based on a first failure mechanism; and

    a second sensor group on a second functional block of the integrated circuit chip comprising second sensor structures that are configured to detect a measure of different amounts of wear based on a second failure mechanism different from the first failure mechanism.
