New options for BOM importing

From XJDeveloper 3.6 a new BOM data type is available in the BOM Import dialog, the “Unfitted” device field. Any devices with an entry in a column assigned to this are suggested under the “Suggested Unfitted Devices” category on the Categorise Devices screen. […]

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. […]

Specifying bus access during XJRunner tests

Alongside other improvements to the XJRunner test setup, XJTAG v3.5 has a new interface to specify bus access from the test system using the XJRunner Setup screen. When you edit a test there is now a Bus Access tab on the dialog, which allows full control of which pins are used to read and/or write from a bus during the test. […]

New website

We have launched a new website today. As a result, existing logins for support and downloads will no longer work. Customers will need to create a new account, by clicking Sign in at the top and then clicking Register. You will immediately be able to submit support enquiries. Assuming you're in maintenance, XJTAG will activate [...]

Common errors when updating files with the new XJEase Library

With the new XJEase Library we have made some fairly extensive changes to reduce code duplication, to improve test coverage, and ease of use.  If you have used additional code files from the XJEase library to create your own test scripts you may find that updating to the new versions of these files causes errors in your project.  Below are the common errors you might see and how to fix them. […]

Why categorise resistors, inductors, links and fuses?

Recently one of our newer customers started on their first solo board setup. They had previously seen XJTAG demonstrated and had also had their initial board setup done by an XJTAG engineer. When they came to setting a board up for themselves they tried to follow the path that the XJTAG engineer had talked them through – […]
