RESet AU Faults

Re-classifies the faults in certain untestable categories.

The Reset Au Faults command re-classifies the following untestable faults as
shown:

Deterministic fault simulators classify some untestable faults differently
depending on the algorithm. You can use the Reset Au Faults command to align
those potentially misclassified faults.

When the command changes the fault classification, the tool then has the ability to
analyze and further reclassify each previously-untestable fault. Allowing the tool
the ability to analyze and reclassify those particular untestable faults increases the
tool’s efficiency.
