Analyze Fault

Command Dictionary

 

 

The DFTInsight schematic view contains annotations for the following cases as required:

oSuccessful ATPG — All gates that sensitize the fault effects to an observable point are added to the gate list. The pins on these gates are annotated with the simulated value that results from the pattern that was created.

oUncontrollable Fault Site due to Forbidden Conditions — All gates that prevent the fault site from attaining the required state are added to the gate list. The pins on these gates are annotated with the constrain_value data.

oBlocked Fault Site due to Forbidden Conditions — All gates that sensitize the fault effects to the blockage point and all gates that prevent the blockage points from attaining the necessary values are added to the gate list. The pins on these gates are annotated with the constrain_value data.

Examples

The following example performs test pattern generation, then performs an analysis to determine why the tool did not detect a stuck-at-1 fault at pin i_1006/i1 during a previous run:

set system mode atpg add faults -all

run

report statistics report faults i_1006/i1

analyze fault i_1006/i1 -stuck_at 1
