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
