A new version of XJTAG – version 4.3 – has been released, containing updates and new features. It is now available from our website for users who are in maintenance.

Main Features

This article summarises the main features in XJTAG 4.3. Blog articles with more details on these features, and some of the many other enhancements, will follow over the coming weeks.

Support for FTDI JTAG controllers

XJTAG applications now have support for the range of JTAG controllers manufactured by FTDI. These devices can be mounted as chips on the unit under test and allow a simple USB cable connection to the PC running tests. Alternatively a cable containing one of these devices can be used instead of a conventional JTAG controller to provide access to a single JTAG chain.

Cloud-based Evaluation licences

XJTAG 4.3 adds a new licensing mechanism. In addition to the existing licensing mechanisms that use either the XJLink controller or FlexNET network licensing, support has now been added for an internet-based licensing system. When used in conjunction with an FTDI JTAG controller it means evaluations of XJTAG can now easily be made without needing XJTAG to send any hardware to the customer at all.

XJEase improvements

A number of improvements have been made to the XJEase language. In particular, parameters to the CALL statement no longer need to be constant, so the target function can be resolved at runtime, giving greater flexibility in calling functions in test device files. In addition the restriction that CALL statements could not be used from one test device file to call functions in another has now been removed.

XJRunner XJLink selection

XJRunner now has an option on the Tools menu which allows you to select which of the attached JTAG controllers you want to use for running tests, if you have more plugged into the PC than you wish to use.

Other features

A large number of smaller improvements are part of XJTAG 4.3. These enhancements and bug fixes aim to increase reliability and improve ease of use.
