XJDeveloper — 先进的图形界面

XJDeveloper是简单快速地安装和测试的图形化工具。在制造过程中,随着XJDeveloper 通过在产品设计中书写的脚本的重复使用,可缩短产品上市的时间。

一个内嵌的连接性测试,结合非JTAG的XJEase,核对电路板的短路开路故障。使用XJDeveloper可简单创建或是定制测试。通过DFT分析可以查看电路板的测试覆盖率,同时内置了网络表浏览器,Layout ViewerSchematic Viewer提供简单的界面,查看器件之间的连接性。Watch Demo Video

XJDeveloper 可用于JTAG器件(例如CPLD,FPGA)与非JTAG器件(例如 EEPROM,Flash)之间的编程 。

高级连接测试

作为脚本的一部分,一个拥有专利的连接测试能在板上运行。通过利用板上器件的特征和内连关系的知识,XJTAG能够实现比其它JTAG系统更高的测试精度。
通过监控器件案的状态,XJTAG还可以对发现的任何故障提供有关定位和故障的精确特征的更多信息。除此以外,输出信息中还包含了一些可点击的链接,使故障非常容易地就能在Schematic ViewerLayout Viewer中显示出来。

免费器件测试库

安装XJEase库包含测试上千个设备,包括Flash和其它器件编程的实例。即使用户从未使用过XJTAG,无需额外的编程,建立一个完整的测试工程也是可能的。

用户如果不能找到你特定的器件文件,可以下载相似器件的文件,并稍微改动一下满足要求。同时,我们也将提供这个方面的服务,满足用户的要求。这里提供一个XJEase代码例子

XJEase — 灵活的、高级的、测试描述语言

具备一个编程语言的所有优点和灵活性,如循环、变量、流程控制,这些都可用于描述器件和电路的测试。在XJEase程序的控制下,通过生成要求的测试序列,XJTAG可以很容易地实现其它JTAG系统无法实现的复杂的测试。

XJDeveloper contains a software debugger for use during XJEase development and prototyping.
This debugger allows you to:

  • 单步运行;
  • 设置或删除断点;
  • 检查和设置变量值;

以器件为中心 — 可重用测试

创建一个XJDeveloper测试系统并不需要了解JTAG的基本知识。用XJEase编写的所有器件测试脚本都是独立于特定的在测器件的。这些测试脚本的依据是器件的透视图,设定一个器件指定引脚的电平水平,运行测试后,所有的引脚的状态是一个预定的结果。然后XJTAG运用他们对电路的知识创建相应的测试序列。这意味着对一个器件的测试脚本开发完成,这些脚本就可以不需任何附加工作就可用于任何电路板上。

测试和编程非JTAG器件

XJDeveloper可以用来测试和编程非JTAG器件,包括Flash、 RAM、 FIFO 阵列, IIC器件, SPI器件和网络控制器。

无需了解JTAG工作机理

如果您不得不创建您的测试,XJDeveloper也可让您的工作变得容易,XJEase已经对器件测试时创建测试向量并实施这些测试的细节进行了抽象,这意味着开发非JTAG器件的测试时简单快捷的。

XJDeveloper将检查待测的器件引脚是否在JTAG器件可访问的网络上,并且JTAG器件引脚必须是可听从控制去访问正确的网络。

而且,一旦您有某个器件的测试文件,只要电路板上有该器件,您就可重用这些文件。

多板测试

测试多板和测试单个板一样容易。只要把网表提供给XJTAG,并且告诉它这些板的相互连接关系,其它事情就交由XJTAG的运行引擎去处理。

运行测试

从XJDeveloper内部可以直接运行测试脚本。当然您也可以根据需要用其它方法运行测试脚本。

XJRunner是生产/服务环境下运行阶段的解决方案,是专门为生产和服务环境设计的,包含有额外的日志、序列码和用户管理功能。它有命令行和图形界面两个版本,以便将XJTAG与其它测试系统集成。

网表

能被XJTAG自动识别的网表格式包括: EDIF 2 0 0, RINF, Protel, PADS-PCB, Cadence Allegro, P-CAD, Genrad, BoardStation (Mentor), Zuken, Protel V2 和50多种格式。如果不能识别用户的网络表格式,我们将帮助转换并为用户提供未来版本的支持。XJTAG Support

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.

      • XJDeveloper can work with hardware licensing or with network licensing (minimum hardware purchase applies).

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.
