Report AU Faults Command Dictionary
For example, a stuck at 0 fault on the output of an AND gate which has one or
more of its inputs constrained to unknown during test is placed in the AU fault
category, and reported in the Uninitialized subcategory. This is because the site
of the fault is constrained to be either 0 or X such that a test is impossible. A
test for the fault would require a 1 on the line which is constrained to be 0 or X
during test. The fault is in the AU category, because the constraint may only
exist in test mode.
•Clock
An optional literal that specifies to display all AU faults that are faults which
only propagate to the clock input of single-port sequential primitives, such as
latch clock inputs and flip flop clock inputs.
•Wire
An optional literal that specifies to display all AU faults that propagate only to
a wired net that does not have wire-and or wire-or behavior.
•Others
An optional literal that specifies to display any AU fault that does not belong to
one of the specific categories (Blocked_constraint, Clock, Tied_constraint,
Tristate, Uninitialized).

Note
UI faults must be in Uninitialized subcategory, Tied_constraint
subcategory or Others subcategory.
