  Events & Promos  



XJTAG is a leading supplier of IEEE Std. 1149.1 compliant boundary scan development tools. Its JTAG (Joint Test Action Group) development system offers a highly competitive solution for designers and developers of electronic circuits. Utilising XJTAG allows the circuit development and prototyping process to be shortened significantly by facilitating early test development, early design validation, fast development of functional tests and test re-use across circuits that use the same devices. XJTAG is based in Cambridge, UK, and is part of the Cambridge Technology Group.

XJTAG was the first boundary scan solution to offer a common platform for use by design and development engineers, test engineers, contract manufacturers and field test engineers, providing testing of not only JTAG-enabled devices but non-JTAG devices as well.

  XJTAG Development System  

The XJTAG Development System is an established test suite with a range of software and hardware products that enable you to debug, test and program electronic circuits quickly and easily. The system works with devices that conform to the IEEE 1149.1 and 1149.6 boundary scan standards.

XJTAG is developed in Cambridge (UK) and it is supported worldwide, to enable developers and test engineers to unlock the potential of boundary scan. XJTAG can help you speed up the design and development process and improve your debug and testing throughout the whole product lifecycle.

  XJInvestigator Investigate the causes of test failure  

XJInvestigator allows you to diagnose manufacturing problems on failing boards. Combining the test capabilities of XJRunner and XJAnalyser with additional diagnostic functionality, XJInvestigator is the boundary scan tool to use at your repair/rework station.

  XJDeveloper Advanced graphical interface  

XJDeveloper is a graphical application that allows you to quickly and easily set up and run tests on your circuit. With XJDeveloper you can reduce your time to market by reusing your test scripts all the way through the product design process and then in manufacturing.

The simple drag-and-drop interface allows you to set up your JTAG chain and categorise all of the non-JTAG devices in your circuit easily. XJDeveloper includes built-in Layout Viewer, Schematic Viewer and DFT Analysis tools, along with Netlist Explorer to view connectivity between devices.

XJDeveloper can also be used to program both JTAG devices (e.g. CPLDs, FPGAs) and non-JTAG devices (e.g. EEPROMs, Flash).

  XJAnalyser Graphical Circuit Interaction  

XJAnalyser is a powerful tool for real time circuit visualisation and debugging. It provides a graphical view of JTAG chains, giving you complete control, on a pin-by-pin basis, of both pin state (either driven as an output or tristated as an input) and pin value (either high or low when driven), and it has the facility to run SVF and STAPL / JAM files.


  XJRunner Run-time environment for XJEase 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.


  XJAPI Software & Hardware Interface  

The XJAPI is a simple-to-use DLL Application Program Interface (API), designed to give you low-level access to the JTAG chain via either the XJLink or the PXI hardware, allowing easy integration with a wide range of other systems such as development/evaluation boards, test systems...

The USB to JTAG hardware and software interface is composed of a high-speed USB to JTAG hardware module (XJLink/XJLink2) and the XJAPI, allowing you to access and control the JTAG chain directly.

The PXI to JTAG hardware and software interface is composed of a high speed PXI to JTAG hardware module and the XJAPI.

We can develop bespoke end user applications using the XJAPI to meet your requirements.
