Set Bus Handling
Tools Supported: FastScan and FlexTest
Scope: Atpg, Good, and Fault Modes
Usage
SET BUs Handling {Pass | Fail | Abort} {bus_gate_id#... | -All}
Description
Specifies the bus contention results that you desire for the identified buses.
The Set Bus Handling command preassigns the contention check handling result
that you desire during simulation for the buses that you specify. Upon invocation,
the tool automatically calculates the bus contention handling as documented under
the Set Contention Check command description. The tool rejects (from the
internal test pattern set) ATPG-generated patterns that can cause bus contention.
The Set Bus Handling command allows you to override the automatic contention
calculations, thereby changing whether or not the tool performs a simulator-based
check using such a pattern.
The tool resets the bus contention handling back to the automatically calculated
value whenever you make a change to the modeling that requires the tool to
perform a complete reanalysis of the contention mutual exclusivity (such as
changing the net resolution or the pin constraints).
Arguments
•Pass
A literal that specifies for the tool to not perform bus contention evaluations on
the buses that you identify and to treat them as if they had passed. This allows
the tool to retain patterns that it would otherwise reject due to a contention
check failure.
Note
Overriding the automatically calculated contention check handling
results can cause trouble downstream if there is a problem with the
design that required modification due to the bus contention.
