Set Stg Extraction Command Dictionary

Set Stg Extraction

Tools Supported: FlexTest

Scope: All modes

Usage

SET STg Extraction ON OFf

Description

Specifies whether FlexTest performs state transition graph extraction.

The Set Stg Extraction command controls whether FlexTest automatically performs state transition graph extraction during the pre-processing of the non- scan circuit. State transition graph extraction can reduce the effort of state justification during ATPG. However, it can also lead to an increased test set size. Thus, if you are primarily concerned with the size of the test set, you should turn state transition graph extraction off.

This command replaces the old Set State Learning command.

Arguments

∙ON

A literal that specifies for FlexTest to automatically perform state transition graph extraction for non-scan circuits. This is the default behavior upon invocation of FlexTest.

∙OFf

A literal that specifies for FlexTest to not perform state transition graph extraction.

Examples

The following example turns off the state transition graph extraction:
