XJRunner — Run-time production test environment

Run-time environment for IEEE 1149.1 tests

XJRunner is the specialised run-time environment for executing pre-compiled XJDeveloper projects. With a range of special features it is particularly aimed at board manufacturers and in-field support.

In one package, you have interconnect testing, in-system programming, non-JTAG device testing, serial number handling and configurable log files for your audit trail.

It has an easy-to-use GUI, with all the testing capabilities of XJEase.

Key Benefits

  • Improves your QA through configurable logging
  • Allows you to retain power of control on how boards are tested by third parties
  • User-friendly environment reduces your training costs for production operatives
  • Ability to test multiple boards, simultaneously, by using multiple XJLinks


  • Run-time environment for XJDeveloper tests
  • Simple, controlled test execution
  • Handles a variety of serial number systems
  • Log files for audit trail
  • Optional restricted access for test-only users
  • Fault Dictionary to capture the expertise of your engineers
  • Two modes for simultaneous board testing
  • Board statistics and fault trend analysis
  • Physical location of faulty nets can be displayed visually in the Layout Viewer
  • Circuit design around faults can be viewed in the Schematic Viewer*

Simple, secure & audited production testing

XJRunner tests are loaded from a single encrypted file that contains a compressed version of the XJDeveloper test system created by your design or test engineers. This means that your tests cannot be changed in the production environment. The consistency that this ensures for your testing process can be seen when reviewing the configurable log files that can be produced whenever you test a board.

XJRunner has a simple Run/Stop, Pass/Fail interface which makes first pass testing a simple point-and-click operation, ideal for the production line. Configurable run-time messages can tell the tester about any required procedures both before and after testing each board.

Using multiple XJLinks or the 4-port XJQuad, save time by testing a batch of boards simultaneously as a group. Alternatively, run through them independently by continuously unplugging one board that has finished testing and plugging in a new one whilst tests are still running on the other ports.

User Management

XJRunner has different levels of users, from Basic users who can simply run a complete set of tests on a board, to Advanced users who can carry out more complex testing and manage projects. Each operator can have a separate login. This allows you to restrict each operator’s access to the XJRunner features they have been trained to use; it can also be used to identify the operator for audit.

Powerful, flexible, diagnostic testing

After a faulty board has been identified on the production line with a default set of Pass/Fail tests, advanced users can then pinpoint faults by running additional tests and debug procedures. They can also choose to run a particular test, or set of tests, a number of times, or even run a test continuously to help diagnose particularly tricky or intermittent problems on a board.

XJRunner also provides statistics on the percentage of boards that have passed/failed as well as Fault Trend Analysis, highlighting tests prone to failure.

Layout & Schematic Viewers included

If any faults are found when running tests, the Layout Viewer and Schematic Viewer* can be used to locate and understand the faults on the board by showing the schematic design and the physical routing of nets, which highlight the potential problem areas. You can also quickly find any component, pin or net in your circuit when trying to pinpoint a fault.

In order to use the Layout Viewer you’ll need to use ODB++ when developing the project or the target system.

* For manufacturers to use the Layout and Schematic Viewers in XJRunner, you have to explicitly export the relevant information from XJDeveloper. Conversely, if the information needs to be kept confidential, do not export it to XJRunner.

Log Files

All the output from tests is logged. There is a range of logging options, to choose both what is logged (time, date, serial number, user information, etc.) and how the logs should be grouped (e.g. keep all output for the same board in the same file).

Serial numbering

XJRunner can also program and log serial numbers, or other forms of identification such as MAC addresses. These can be generated by XJRunner, taken from the packaged XJDeveloper system, or be input directly (e.g. from a bar code reader).

Easily Portable Testing

All of the files needed to run tests on a board are packaged together in one XJPack file, making it easy to transfer tests between different computers and sites.

Recommended system requirements
