Description

Updates the current fault population to include or exclude the faults contained in the specified fault file.

The Load Faults command affects the current fault population by either adding or removing faults which you specify in an external fault file. Because you must identify the faults before performing an ATPG or Fault simulation, this command is useful when you have a large number of faults to identify.

The format of the fault file data can be either in a three, four, or five column standard format. Regardless of the format, the Load Faults command uses only the information in the first, second, and third columns. The file follows the format illustrated below:

stuck_at fault_class pin_pathname (cell_name) (net_name)

∙stuck_at

The first column must be the stuck-at value.

∙fault_class

The second column must be the fault class value, but only if you use the -Restore option.
