Tools Supported: FastScan

Usage

SET DEcision Order -NORandom -Random

Description

Specifies how the ATPG determines and uses observation points.

The Set Decision Order command specifies whether ATPG makes random choices when faced with a decision.

Note

Arguments

You may be able to resolve AU and UO faults by restoring the (invocation default) full handling of observation points with the Set Decision Order command and rerunning the ATPG. However, while this may increase your test coverage, it also increases the run time.

-NORandom

A required switch that causes the ATPG to make the easiest choice when faced with a decision. This is the default upon invocation of the tool.

-Random

A required switch that causes ATPG to make random decisions when faced with a choice, rather than choosing the easiest. This causes variation between patterns, tending to give a more compact vector set at the risk of creating more ATPG aborts.
