Set Bus Handling Command Dictionary

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).

Note

Arguments

∙Pass

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.

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.
