XJDeveloper — フルテスト 開発環境

XJDeveloper は、基板テストの設定・実行を、簡単・迅速に行なえるグラフィカルなツールです。XJDeveloper のテストスクリプトは、製品設計時のデバッグから製造工程まで再利用が容易で、製品市場投入までの期間を削減できるようになります。

XJDeveloper に搭載されるコネクションテストと、JTAG 未対応デバイスに対応する XJEase により、基板実装のオープン・ショートエラーを検査します。テストの開発やカスタマイズが容易なXJDeveloper では、ネットリスト・エクスプローラ機能によりデバイス間の接続情報を提供し、レイアウトビューア回路図ビューア、DFT(デザインforテスト)機能によりテストのカバレッジを解析することも可能です。XJDeveloper 動画デモ

XJDeveloper は、JTAG デバイス(CPLD, FPGAなど) や、JTAG未対応デバイス(EEPROM, Flashなど)へのプログラミングもサポートしています。

アドバンスド・コネクション・テスト

独自開発の接続テストが スクリプトの一部として基板上で行われます。回路内のデバイス間の相互接続と特性を考慮に入れて、XJTAGは他の多くのツールより高い割合のテストを実 施します。また、回路内のデバイスの状態をモニターすることで、不具合発生場所に関する詳細な情報と不具合の正確な種類を得ることも可能です。Clickable links to the Schematic Viewer and Layout Viewer assist the user to understand or visualise the faults on a board.

テストは、ライブラリとして無償で提供しています

A large number of device files for testing non-JTAG devices are available in the installed XJEase library, including examples of programming. テストプログラム開発環境に含まれる XJEase library には、DDRやFlashなどメモリを代表に、あらゆるJTAG 未対応デバイスのテストプログラムが提供されます。これにより、JTAGテストを始めて導入する場合でも、プログラミングすることなく完全な機能テストを行えます。また他社製品のように追加費用も求めませんので、安心してJTAGテストに取組んでいただけます。ここではXJEase言語を例として説明していますが。

If you can’t find a file for your exact device, you can start with the file for a similar device and make a few changes to adapt it to yours. We also offer a consultancy service to design tests to your exact requirements.

XJEase — 柔軟な、高級レベル言語でテストを記述

変数、ループ、実行制御といった全てのプログラム言語の柔軟な強みが、デバイスや回路のテストを開発するために使用されます。XJEaseの高レベ ルなプログラムを用いて必要なテストパターンを生成し、他のJTAGツールでは不可能であった複雑なテストが容易に開発可能です。

XJDeveloper contains a software debugger for use during XJEase development and prototyping.
クラシックスタイルのデバッガを包括しており、以下の機能が使えます :

  • コード一行毎のステップ実行
  • ブレークポイントの削除とセット
  • コード内での変数値のセットと確認

デバイスセントリック-再利用できるテスト

XJDeveloperのテストシステムの構築には、JTAG技術そのものへの理解は不要です。XJEaseを使って書かれた全てのデバイステストプログラムは、テスト対象回路に依存しません。デバイスの視点で書かれます:これは、テスト実行に必要なピンのレベルと、期待値として関連するピンの状態を規定します。次にXJTAGは、回路に対する情報を用いて、所要の入力を行うテストパターンを作成します。つまり、一度デバイスに対するテストプログラムを作成すれば、どんな回路に対しても追加の作業無しに再利用されます。

JTAG未対応デバイスに対するテスト、プログラミング

XJDeveloper を用いて、JTAG未対応デバイスのテスト、プログラミングができます。 例えば、Flash, RAM, FIFO, IIC devices, SPI devices and Ethernet controllers など。

JTAGの動作への理解は不要

JTAG未対応デバイスへのテストを作りたい場合でも、JTAGの仕組みや動作を意識することなくプログラミングできるようになっている為(高級言語による抽象化)、容易かつ迅速に開発することができます。

XJTAG は、JTAGデバイスからアクセス可能なネット上のテスト対象デバイスのピンをチェックし、適切なJTAGデバイスのピンを操作できるようになっています。

同様に、一旦デバイスのテストプログラムを入手すれば、そのデバイスが他の回路の一部である限り、再利用可能です。

複数の基板

複数基板のテストも、単一基板のテストと同様に簡単に実行可能です。複雑な結合手順はありません。XJDeveloper にネットリストを設定し、相互接続の状態を設定するだけです。それ以外の全ての作業は、実行時に XJTAG が処理します。

テストの実行

テストはXJDeveloper からも実行させることや、目的に応じた別の実行手段を提供。

XJRunnerは、製造検査やメンテナンスサービスなどの現場用のテスト実行ツールです。これは、基板製造業者や現場でのインフィールドテスト向けに特化した製品で、テスト結果のログ機能、シリアル番号の生成機能やユーザーの管理機能が追加されています。他のテストシステムへ統合する為のインターフェイスも用意しています。

ネットリスト

A netlist contains connectivity information for a board. XJTAG supports a wide range of netlist formats that the system automatically parses, identifies and accepts. You should be able to use any ASCII netlist; however if your netlist is not recognised, please contact XJTAG Support and we will be happy to convert it to a format that works and add a parser to a future release.
More about netlist formats on the XJTAG Blog.

Testing with no netlist

If you don’t have the netlist for a board you need to test, XJDeveloper allows you to base a test system on the BSDL files for the JTAG devices on the board rather than forcing you to use a netlist. The system can then automatically learn from a golden board the connections between the JTAG devices for use during connection test. You can also add additional non-JTAG device such as RAM, flash or devices on peripheral busses such as I²C and SPI, in order to extend the test coverage.

Technical questions

What files / data do I need to start working with XJDeveloper?

The minimum needed is the BSDL file for at least one of your JTAG devices (available from the device manufacturer).

Results will be much better and test coverage easier to achieve if you have a netlist for the board you wish to test. This is usually exported from the board design (EDA) tools.

If your EDA tools support export in ODB++ format, by using this as the netlist, XJDeveloper will also have access to layout information on your board to improve how it shows you problems.

If you have a Bill of Materials (BoM) for your design, XJDeveloper can use the information in it to help you improve your setup and save time in deciding how to categorise devices.

Providing the schematics (in PDF format) to XJDeveloper also allows it to help better during board setup.

You do not need the board you wish to test in order start the setup, though you will want to verify your tests on real hardware at some stage.

What netlist formats does XJDeveloper support?

Our recommendation is that customers use ODB++ board data because this contains both netlist and layout information and almost all CAD tools can generate ODB++. However, XJDeveloper supports over 80 formats of netlist, so if you do not have ODB++ we simply suggest you try using yours. If XJDeveloper does not recognise it please send it to us, we will gladly convert it to one that we can support, and we will also add support for your format into the next release of XJTAG software.

Can I update the netlist on an existing project?

Yes, simply edit the board to use the new netlist. XJTAG will migrate all the existing setup to the new netlist.

I have modified the board during bring-up – can I represent this in XJTAG?

XJTAG has the ability to add connections (e.g. wire mods) to the circuit model, or to disconnect parts of the circuit (e.g. cut tracks) in addition to being able to mark devices such as resistors and connectors as fitted or unfitted.

How easy is it to write my own tests?

We think it is very easy. But mostly you won’t have to, because the XJEase library contains a large number of common devices such as RAM, Flash, etc.

The XJEase language is designed so that you work by thinking about the device you are testing, so if for example you want to set the nOE pin high on a chip, that is how it is described in XJEase (SET nOE := 1; ) No need to worry which JTAG device the pin is connected to, or how it is connected, XJTAG works that out for you.

The XJEase language means you can do more than just play back a pre-defined set of vectors – you can use IF or WHILE statements to make decisions during tests, and even call other programs from within the tests.

The library of tests provided with XJEase contains a wide selection of devices, and you can see all of the XJEase source code for these tests. So if you want to find out how to do something for a new device, look in the tests we supply for a similar device, and copy or modify it.

The XJEase library also contains functions for using protocols such as I2C or SPI, and useful functions for tasks such as reading programming information from files in various formats, doing maths operations, etc.

What test coverage can I get using XJTAG tools?

The best answer we can give is to suggest you try XJTAG and let XJDeveloper generate a test coverage report for your circuit. XJDeveloper can also give some indications of parts of the board which are not tested or for which testing could be improved.

If you would like to take advantage of a free DFT Coverage Review of your initial design, our experienced test engineers will be happy to provide an analysis of boundary scan testability and make suggestions for improvements to maximise test coverage. Contact us now.
