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.

Caution

Arguments

∙pathname

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.

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.
