Description
Specifies the fault model for which the tool develops or selects ATPG patterns.
The Set Fault Type command specifies the fault model type for which you want
the tool to develop ATPG patterns. The default upon invocation of the tool is
Stuck.
The fault sites of all models are the input and output pins of the design cells in
addition to external pins. The tool uses the values 0 and 1 for all fault models to
indicate the type of fault at the fault site. Each fault model has its own separate
fault collapsing according to the model’s rules of equivalence.
When you change the fault type, the tool deletes both the current fault list and
internal pattern set.
For more information on the different fault models, refer to the Scan and ATPG
Process Guide.
