Parameter Properties/Degradation Targets
Tests: The tests in the subsite that have output values assigned.
Output Values: The name of the output value.
%: The percent of change between the post-stress output value reading compared to its pre-stress
output value reading. The % Change is calculated and listed in the subsite Analyze sheet. The
percent of change for post-stressed output values is calculated as follows:
% Change = ABS[(Post-Stress Reading − Pre-Stress Reading) / Pre-Stress Reading x 100]
Abs: The value of the absolute change of the post-stress output value reading compared to its pre-
stress output value reading. Abs is calculated and listed in the subsite Analyze sheet as Abs Change.
The absolute change for post-stressed output values is calculated as follows:
Abs Change = ABS[Post-Stress Reading − Pre-Stress Reading]
Degradation Targets: An output value is assigned as a target in percentages or an absolute value
and is evaluated for degradation. When all targets for a device are reached, that device is no longer
tested. Subsequent cycles bypass the device tests that reached all its targets. Refer to
Degradation
targets (on page 6-168) for more information.
