Small delay faults receive more and more attention, since they may indicate a circuit reliability marginality even if they do not violate the timing at the time of production. At-speed test and faster-than-at-speed test (FAST) are rather expensive tasks to test for such faults. The paper at hand avoids complex on-chip structures or expensive high-speed ATE for test response evaluation, if aging monitors...
The failure rate of XLPE (Cross-linked polyethylene) cable joints is higher than that of cable in distribution systems due to bad environmental conditions, improper installation, and aging. To evaluate the failure and degradation of a cable joint via partial discharge (PD) detection, a 10kV XLPE cable joint was selected as the experimental sample, which was found partial discharge by field testing...
