About This Manual

Overview

FastScan and FlexTest are Mentor Graphics ATPG tools which are an integral

part of the Mentor Graphics Design-For-Test solution.

FastScan is a comprehensive combinational Automatic Test Pattern Generation

(ATPG) system optimized for full scan designs. It offers the highest speed and

accurately measured high test coverage to guarantee your product quality and

reliability.

FlexTest is a high performance sequential Automatic Test Pattern Generation

(ATPG) system that allows you to create a set of test patterns that achieves a high,

accurately measured test coverage for your cycle-based circuits.

Optionally available with FastScan and FlexTest is Mentor Graphics DFTInsight

which can translate a specified portion of a netlist-based design to schematic form.

DFTInsight adds the ability to graphically investigate and interact with designs,

thus facilitating testability debugging efforts.

This manual contains information on each of the FastScan, FlexTest, and

DFTInsight application commands. Additionally, the manual contains reference

information specific to each of these applications. For procedural information on

how to use FastScan, FlexTest, or DFTInsight in the ASIC/IC design

environment, refer to the Scan and ATPG Process Guide.

This manual is divided into the sections and appendices that follow:

• Chapter 1 — Introduction - briefly describes the inputs, outputs, and

features of FastScan, FlexTest, and DFTInsight.

• Chapter 2 — Command Dictionary - lists the detailed information for

each command.

Overview About This Manual

• Chapter 3 — Shell Commands - lists the detailed information on the

FastScan, FlexTest, and DFTInsight invocation commands.

• Chapter 4 —Test Pattern File Formats - describes the test pattern file

format.

• Chapter 5 —Distributed FlexTest - describes how to divide ATPG

processes into smaller sets and run these sets simultaneously on multiple

workstations.

• Appendix A —Timing Command Dictionary - describes how to create a

timing file and apply it to the test pattern set.

• Appendix B —FlexTest WDB Translation Support - describes

FlexTest’s usage of the “wdb2flex” utility to translate Waveform Databases

to FlexTest Table Format Patterns.

The DFT applications use Adobe Acrobat Exchange as their online

documentation and help viewer. Online help requires installing the Mentor

Graphics-supplied Acrobat Exchange program with Mentor Graphics-specific

plugins and also requires setting an environment variable. For more information,

refer to the section, “Setting Up Online Manuals and Help” in Using Mentor

Graphics Documentation with Acrobat Exchange.
