Command Dictionary Set Bus Handling
FastScan and FlexTest Reference Manual, V8.6_4
2-439
• Fail
A literal that specifies for the tool to treat the buses that you identify as if they
had failed the bus contention evaluations. This causes the tool to reject patterns
that it would otherwise retain due to passing the contention check.
• Abort
A literal that specifies the bus aborted the bus contention evaluations before
determining whether the bus passed or failed. This can be used with the
Analyze Bus -Drc command to verify ATPG constraints which you have added
to correct bus failures.
• bus_gate_id#
A repeatable integer that specifies the gate identification numbers of the buses
whose contention handling you want to override. If a bus is cascading, you
must specify the dominant bus.
• -All
A switch that specifies for the tool to reset the bus contention handling for all
buses back to the default.
Examples
The following example turns the bus contention checking off, allowing the bus to
pass the evaluations. However, this action can cause trouble in the future if there
is a problem with the design that required modification due to the bus contention.
