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.

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

Note

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).
