Command Dictionary Add Nofaults
FastScan and FlexTest Reference Manual, V8.6_4 2-85
•-Instance
An optional switch specifying that the pathname arguments are instance
pathnames. In this case, the command places nofault settings on all boundary
and internal pins of the specified instances (unless the -Keep_boundary switch
is used).
•-Module
An optional switch specifying the that pathname arguments are module names
and all instances of these modules are affected.
•-Stuck_at 01 | 0 | 1
An optional switch and literal pair that specifies to which stuck-at values you
want to assign a nofault setting. The choices for stuck-at values are as follows:
01 — A literal that specifies the placement of a nofault setting on both the
“stuck-at-0” and “stuck-at-1” faults. This is the default.
0 — A literal that specifies the placement of a nofault setting only on the
“stuck-at-0” faults.
1 — A literal that specifies the placement of a nofault setting on the “stuck-
at-1” faults.
•-Keep_boundary
An optional switch that specifies that nofault is applied to the inside of the
specified instance/module and creates faults at the boundary pins of these
instances/modules. This option does not apply to nofaults on pin pathnames.
Examples
The following example adds nofault settings to all the pins in the instance so when
you add all faults to the circuit for an ATPG run, the tool will not place faults on
the pins of that instance:
add nofaults i_1006 -instance
set system mode atpg
add faults -all
run
