XJTAG releases boundary scan for Teradyne TestStation

Cambridge, UK, 21 October 2014 — XJTAG, a world leading supplier of boundary scan technology, today announced the release of the XJLink2-CFM and XJLink2-CFMx. The new modules provide Teradyne users with integrated access to XJTAG’s powerful test and programming tools, operating under the control of the TestStation™ test program.

With a JTAG solution installed internally to the TestStation In-Circuit Test System, the complexity and recurring cost impact of fixture-based test can be significantly reduced, while improving overall test coverage.

Integrated Teradyne access will provide you with the following:
  • Advanced JTAG control using available slots on a Teradyne Multi-Function Application Board
  • Use of the same tests in production line ICT and bench-top repair
  • In-system programming of Flash, FPGA and CPLD devices
  • Multi-protocol support – including SPI, I²C



This new integrated product enables streamlining of the production line, while also boosting fault coverage, thanks to the combination of XJTAG’s advanced connection test and non-JTAG device testing/programming with Teradyne’s In-Circuit Test capabilities.

The XJLink2-CFM is an advanced multi-TAP JTAG controller that fits into one of four Custom Function Module (CFM) locations on the Teradyne Multi-Function Application Board. A single or multiple XJLink2-CFMs can be added to the same Teradyne card for supplementary test and program capabilities, for instance testing panels of boards. XJLink2-CFMx expander cards are also available to maximize available connectivity from an XJLink2-CFM controller, from a maximum of 8 fixture-connectable signals when just using the XJLink2-CFM, up to 18 signals by adding one, two or three XJLink2-CFMx cards.

The test interface of the XJLink2-CFM is completely configurable allowing support for almost any programming protocol, not just JTAG devices. Programming speeds close to the theoretical maximum of a device can be achieved using the advanced features of the XJLink2-CFM.

The XJLink2-CFM is compatible with the standard USB XJLink2, so boards can be debugged at a repair station without having to develop a separate test setup. “Adding JTAG boundary scan functionality to the Teradyne test platform provides manufacturers with a robust, comprehensive test and programming environment,” says Simon Payne, CEO XJTAG.

Flexible licensing options also aid ease of use – the product can contain an XJTAG software license and allow standalone operation without additional dongles or network access. The system can also be licensed from a network server allowing the maximum use of XJTAG products without having to move licensed hardware between machines.
