The new XJLink2-CFM and XJLink2-CFMx 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 (ICT) system, the complexity and recurring cost impact of fixture-based test can be significantly reduced, while improving overall test coverage.
Integrated Teradyne access gives users the power of advanced JTAG control using available slots on a Teradyne multi-function application board; use of the same tests in production line ICT and benchtop repair; in-system programming of Flash, FPGA and CPLD devices; and multi-protocol support including SPI and I²C.
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 maximise available connectivity from an XJLink2-CFM controller, from a maximum of eight 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 controller is compatible with the standard USB XJLink2, so boards can be debugged at a repair station without having to develop a separate test setup. Flexible licensing options also aid ease of use – the product can contain an XJTAG software licence 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.
XJTAG offers a free trial and board setup to new users who are interested in taking an evaluation.
