Add Nofaults Command Dictionary
Add Nofaults
Tools Supported: FastScan and FlexTest
Scope: Setup mode
Usage
ADD NOfaults {pathname... [-Instance | -Module] [-Stuck_at {
01 | 0 | 1}]}
[-Keep_boundary]
Description
Places nofault settings either on pin pathnames, pin names of specified instances,
or modules.
By specifying pathnames of pins, instances of, or modules while in Setup mode,
the Add Nofaults command places a nofault setting either on the specific pins or
on boundary and internal pins of the instances/modules. All added nofault pin
pathnames are in the user class. If you do not specify a stuck-at value, then the
tool places a nofault setting on both stuck-at values. When you add faults with the
Add Faults command after you issue the Add Nofaults command, the specified
pin pathnames or boundary and internal pins of instances/modules cannot be sites
for those added faults. Once you add nofault settings, the tool deletes the flattened
model.
Arguments
• pathname
A repeatable string that specifies the pin pathnames or the instance/module
pathnames for which you want to assign nofault settings. If the pathnames you
specify are instance pathnames, you must use the -Instance switch. If the
pathnames you specify are module pathnames, you must use the -Module
switch.
!
Caution
Once you add nofault settings, the tool loses all information added
after flattening the model, such as ATPG functions and
constraints, due to the deletion of the flattened model. Adding
nofault settings should be done prior to flattening the model.
