Degradation targets
You can enable an output value as a target and assign it a target value (in % change or absolute
value). 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. The subsite stops when all targets are reached or
the last subsite cycle is completed.
The testing process for target evaluation is shown in the following flowchart. As a simple example,
assume all the targets for both devices are reached after the first cycle of the subsite test. Following
the flowchart shows that the tests for cycles 2, 3 and 4 are not performed. The subsite test stops.

To enable an output value as a target, refer to Export output values to Analyze sheet (on page 6-
176).
The graph that is plotted is degradation versus stress time.
