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. […]
New XJEase Library format coming soon…
We are in the final stages of a major overhaul of the XJEase device file library and we expect to release it in the next few days. […]
Debugging Connection Test – part 1 (Updated)
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. […]
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 [...]

A new major version of XJTAG – version 3.4 – is now available from our website for users who are in maintenance. […]
Categorising Transistors in XJDeveloper
Transistors are one of the things we get asked about quite a bit: “How should I categorise the transistors in my project?” […]
Making the BSDL library more useful
If you use the BSDL library, a new option will now appear (from XJTAG version 3.3.7) when you categorise a JTAG device in XJDeveloper by selecting it from the library - it will offer to copy the BSDL file into another folder (defaulting to your local project directory). It is up to you whether to [...]
DDR4 support in XJTAG
We have been starting to see questions about support for DDR4 SDRAM devices, which are gradually becoming available. We have published a guide to using JTAG to test DDR4 memory on the XJTAG website. It contains a link to slides used at a recent presentation on the subject. Support for DDR4 devices will be coming soon [...]
Terminations to a reference voltage in XJTAG
This post is to clarify how to specify terminations to a reference voltage in XJTAG. There are two special classes of passive device in XJTAG which represent termination resistors. […]
1149.6 testing in XJTAG
1149.6 testing is coming of age, and though XJTAG has supported IEEE Std. 1149.6 since software version 2.1 (released in 2008) it seems to us that 1149.6 devices are becoming much more common in the last couple of years. […]
