XJTAG targets production sites with XJRunner add-on to boundary scan system

CAMBRIDGE, England, December 22, 2004 XJTAG Limited, a specialist design and test tool developer, has developed XJRunner, a graphical add-on to its XJTAG boundary scan Development System. XJRunner is designed for production sites that need to improve and speed up the testing of densely populated printed circuit boards particularly those with JTAG devices such as ball grid array (BGA) and chip scale devices, flip chips and other high-density packages, which cannot be tested by traditional methods.

“The trend towards smaller, more tightly packed circuit boards with less test points and more JTAG-compliant chips is forcing manufacturers to add boundary scan capability to their test regimes,” says Dominic Plunkett, chief technology officer at XJTAG. “XJRunner has been designed to meet that requirement and to provide a low cost but highly effective alternative to bed of nails testing.”

XJRunner has a user-friendly graphical interface and can be configured to provide simple pass / fail or more sophisticated test routines. XJRunner can be used to test a high proportion of the circuit including JTAG and non-JTAG devices such as BGAs, CSPs, SDRAMs, Ethernet controllers, video interfaces, flash memories, FPGAs (Field Programmable Gate Arrays), microprocessors and many other devices.

XJRunner is packed with features to simplify production line testing. To ensure traceability of boards during manufacture, XJRunner provides logging and support for serial numbers. The file locking capabilities allow information to be shared safely across multiple production lines.

To ensure that the production line administrator has all relevant data to create an XJRunner project and commence testing, XJTAG has also developed XJPack. This enables the designer or developer to automatically select or ‘pack’ all the relevant data for a particular board BSDL files, netlists, XJEase files, pin mapping files etc. for forwarding to the production facility. This is particularly useful when working with contract manufacturing partners.

“XJRunner enables the test systems developed by design engineers to be taken seamlessly forward to production testing and through into field support and repair,” added Dominic Plunkett. “XJRunner offers a cost effective way of extending the power of XJTAG – minus the development capability – throughout the product lifecycle.”

The powerful and easy-to-use XJTAG Development System, launched in 2003, provides a fully-integrated environment which can migrate seamlessly through the product life cycle from early design to field support and repair. XJTAG enables circuit designers to shorten the development cycle and prototyping process by facilitating early test development, early design validation of CAD netlists, fast generation of highly functional tests and test re-use across circuits that utilise the same devices.

XJTAG test scripts are also re-usable and portable across different boards due to the novel device-centric approach that the designers have adopted. Re-usable device tests and the abstraction of device tests from both circuit detail and complexity of JTAG (Joint Test Action Group), mean that designers can quickly develop systems to debug elements of their designs and to functionally test early prototypes.

What is JTAG?

Advances in silicon design, such as increasing device density and, more recently, ball grid array (BGA) and chip scale packaging, have reduced the efficacy of traditional electronic circuit testing methods. In order to overcome these problems and others, some of the world’s leading silicon manufacturers combined to form the Joint Test Action Group (JTAG). The findings of this group were used as the basis for the Institute of Electrical and Electronic Engineers (IEEE) standard 1149.1: Standard Test Access Port and Boundary Scan Architecture and subsequently the standard became known as JTAG.
