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 [...]
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 [...]
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 [...]
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. […]
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. [...]
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 [...]

We understand that sometimes (for your own sanity if nothing else) you need to test that your test equipment is working. For this reason, it is possible to run a health-check on XJLink2 hardware (and XJLink2-based hardware) using the self-test feature available in the XJLink Manager. The self test can be run with or without [...]
Today (31 Mar 2016) we have released a major update to the XJTAG XJEase library. The new library will be installed if you update to version 3.4.5 of XJTAG which is also released today. […]
This post is an update to the original “Debugging Connection Test (part 1)” post – over time several features in XJTAG have changed considerably and may be hard to find by following my original post. […]
