Test Coverage Consultant

Introduction

The Keysight Technologies, Inc. Test Coverage Consultant (KTCC) is a standalone application that can be installed on your Windows PC to enable you to quickly generate test coverage reports for your products.

Powered by Aster Technologies’ Testway engine, the tool can objectively review the board CAD files or board test files to generate a comprehensive report using the PCOLA‑SOQ metrics.

The Keysight Test Coverage Consultant is equipped with the knowledge of Keysight’s In-Circuit test features so that you are able to analyze how the test coverage changes depending on the test features enabled.

This allows you to determine exactly what coverage is available for the tester on your production line equipped with the latest test features.

This quick guide is designed to help you to get the Keysight Test Coverage Consultant up and running on your PC quickly. It guides you through the license redemption procedure and software installation steps and provides instructions for generating a test coverage report of a sample board.

Redemption of Software license file

A certificate of entitlement will be shipped together with the USB Dongle and Software installation CD. Please follow the instructions on the certificate to redeem your software license from Keysight.

Input processors

When you selected either the BASIC or ADVANCED package, you would need to specify one of the input processors that you require. The input processors available are able to read the outputs of the following CAD converters; CAMCAD, Test Expert (or Fabmaster) and TestSight.

Test platforms supported and selection

The Keysight Test Coverage Consultant supports the Keysight In-Circuit test platforms (i3070 and i1000) and, with the Advanced package, the 5DX and SP50 imaging inspection systems as well. These processors are verified by Keysight.

These test platform processors will read the developed tests in the board directory to calculate the actual test coverage of the developed test for the product.

Additional platforms can be obtained from Aster Technologies directly. These have not been verified by Keysight.

How to generate a test coverage report

Compared to other tools, the Keysight Test Coverage Consultant is an automatic and objective tool that provides a complete picture of the test coverage of your product using the PCOLA-SOQ metrics.

Input the test information for actual test coverage reporting

When generating the test coverage of a developed test, only the test directory is required.

When analyzing the actual i3070 test coverage of a test developed board, the actual tests in the board directory and the Keysight Coverage Analyst report is required. The Keysight Test Coverage Consultant will read the Keysight Coverage Analyst report as well as other files in the board test directory to generate the full test coverage report.

When analyzing the actual i1000 test coverage of a test developed board, the board .atd file is required. The Keysight Test Coverage Consultant will generate the test coverage report based on the information in the .atd file.

After selecting Analysis > Test Program Quality, drag the Keysight i3070 or Keysight i1000 icon into the Test Line. Right click the icon and select Test Settings. Then select the Start.htm for i3070 or ATD file for i1000 and click Analyze to generate the actual test coverage report.

Input board data for test coverage prediction

The Schematics, bill of materials (BOM) and especially the output of a CAD translation tool are essential information for an accurate test coverage prediction. As a minimum, the output of a CAD translation tool is required.

The supported CAD translation tool outputs are CAMCAD, Test Expert (formerly known as Fabmaster) and TestSight.

Using the CAD conversion tool, the testpoints should be selected so that they can be taken into account by the Keysight Test Coverage Consultant. The component value and tolerance should also be updated with the latest BOM.

Without the processing by CAD translation tools, the correct CAD input processor needs to be purchased from Aster directly to read the CAD layout file. The BOM can be read using a text Grammer file indicating the locations of the part number, value, tolerances, etc., that you create to indicate to the Keysight Test Coverage Consultant where to find the information in the BOM. The Keysight Test Coverage Consultant has a in-built tool to select the available testpoints on the design.

Digitize schematics

The advanced version of the Keysight Test Coverage Consultant, is able to digitize the .pdf format of the schematics file. This allows the views to be updated to the selected component even in the schematics. In this way, you can get a better understanding of the surround components around the selected component. The schematics must be saved in a searchable PDF format.

Display Netlist graphically

The advanced version of the Keysight Test Coverage Consultant can also display the Netlist in graphical form. By selecting a particular node, you can see the test access at this node, the attached components as well as the opposite or adjacent node across the components on this node. This gives you another view of the surrounding of the component based on the selected node.
