Scope: Setup mode
Usage
ADD OUtput Masks primary_output...
Description
Ignores any fault effects that propagate to the primary output pins you name.
The tool uses primary output pins as the observe points during the fault detection
process. When you mask a primary output pin, you inform the tool to mark that
pin as an invalid observation point during the fault detection process. This
command allows you the ability to flag primary output pins that do not have
strobe capability. The tool classifies the faults whose effects only propagate to that
observation point as Atpg_Untestable (AU).
