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 the same time.  The test is implemented by driving the net high or low and then checking that the value read from the net changes to reflect the value driven.

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 reassure our customers that if you are able to work, we are able to support you. […]

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 this date, with some organisations opting to purchase extended support. We will therefore ensure that XJTAG continues to work on Windows 7 for the time being. However, due to Windows 7 not being in mainstream support, our products will not receive the same level of testing as they do for Windows 10 and we would encourage our users to upgrade to Windows 10 when possible.

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 boundary scan cells.   […]

Categorising devices: Ignore, Unfitted, or Uncategorised?

One of the questions we are commonly asked by new users, but also by users who have not used XJTAG for a while and are coming back to it, is about the differences between device categorisations in XJDeveloper. […]

Testing XJLink hardware

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 a loopback connector but should never be run with the XJLink connected to test hardware. […]
