  • Monitoring of interconnect reliability using a programmable device
    Patent number: 8093921
    Abstract: In one embodiment, the reliability of the L2 power and/or ground sub-arrays of contacts of a functional integrated circuit device is verified by applying a reference voltage to a selected contact in sub-array and sequentially measuring the voltage at other contacts in the sub-array. If the voltage levels are greater than a threshold voltage level then the functional integrated circuit device is verified as being reliable.
    Type: Grant
