Description
Adds faults into the current fault list.
The Add Faults command adds faults to the current fault list, discards all patterns
in the current test pattern set, and sets all faults to undetected (actual category is
UC). When you enter the Setup mode, the tool deletes all faults from the current
fault list. Furthermore, if you change the fault type, the tool deletes all faults.
The tool only adds one instance of any given fault, ignoring any duplicate faults.

• object_pathname
A repeatable string specifying pins, instances, or delay paths whose faults the
tool adds to the current fault list.
• -All
A switch specifying that the tool add all of the faults on all model, netlist
primitive, and top module pins.
