XJTAG version 3.12
A new major version of XJTAG – version 3.12 – is now available from our website for users who are in maintenance. […]
Placing an Infineon Aurix™ TriCore™ TC3xx Microcontroller into Boundary Scan Mode
Some devices need more than a standard Test Reset sequence to enter the state when they behave as described in their BSDL file and boundary scan can run. Infineon’s Aurix TriCore TC3xx microcontroller family is one such group. […]
XJTAG statement about log4j vulnerability
There has been a lot of press about the recently discovered vulnerabilities in the Apache log4j software component, and companies are starting to do due diligence about whether they are exposed to related exploits due to its inclusion in software that they own. XJTAG would like therefore to reassure customers that no XJTAG software uses [...]
Installing XJTAG when Microsoft Defender Controlled Folder Access is enabled
Microsoft Defender has an optional feature called Controlled Folder Access, which is designed to protect sensitive folders from being modified by malicious software. This feature is not switched on by default and is only available if you are using Microsoft Defender Antivirus or Microsoft Defender for Endpoint; if you’re using a third party antivirus solution [...]
Stuck-at testing on 1149.6 pins
One of the standard types of testing that is done in XJTAG’s Connection Test is to detect stuck-high and stuck-low faults (shorts to power/ground). Using the IEEE 1149.1 JTAG standard this can be done providing the net has full IN/OUT functionality – that is to say it can both drive output and read input at [...]
Dealing with the Covid-19 situation
We wish all of our customers the best at this difficult time, as everyone tries to keep their production and development moving, amidst supply line issues and staff being temporarily unavailable due to illness or the need to isolate themselves. XJTAG is of course affected by the current situation too, but we would like to [...]
Windows 7 Support
Microsoft is ending mainstream support for Windows 7 on January 14th, 2020. This means that after this date updates to fix security issues will not generally be available and so machines running Windows 7 will be more vulnerable to security risks and viruses. We understand that many users will choose to continue using Windows 7 after [...]
An easier way to run SVF or STAPL files in XJTAG projects
There are new global functions in XJTAG 3.6 which are always available to use (like the built-in Connection Test). The functions RUNSTAPL and RUNSVF allow users to run programming files without having to write any further XJEase to enable this. […]
Categorisation Suggestion Improvements
From XJTAG 3.6 onwards the suggested device categories on the Categorise Devices Screen have been renamed and expanded, with separate categories for different types of resistor packs. In addition, the “Suggested Resistors – Other” category now displays the reason for any resistor’s inclusion using a separate “Reason” column, to make the inclusion of a device into this category easier to understand. [...]
Custom cells in BSDL files
The JTAG standard contains definitions for various different types boundary scan cells, each of which have different capabilities, and these allow an IC vendor to accurately describe how the pins on their chips behave. But because not every eventuality can be foreseen the JTAG specification also allows IC vendors to create their own types of [...]
