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 [...]
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 [...]
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. […]
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 [...]
Transistors are one of the things we get asked about quite a bit: “How should I categorise the transistors in my project?” […]
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 [...]
Windows XP was released in October 2001 and has been one of Microsoft’s most successful operating systems. […]
When using JTAG with a Device Under Test (DUT) connected to a bed-of-nails test fixture, often little attention is paid to the way the JTAG signals are wired. This article (published in SMT magazine last year) gives a helpful explanation of why it is important to get this right, and gives tips for best practice.
In Version 3.0.2 and later an additional Settings tab has been added to the XJRunner Setup screen in XJDeveloper. This tab, labelled “Functions”, […]
We recently had to support a customer who was unable to run XJTAG 3.1 on an older PC. It turned out that the processor in the PC in question did not support SSE2 instructions. During the development of v3.1 we upgraded the compiler we use to build XJTAG and it now uses these instructions to speed up execution. SSE2 instructions were introduced with the Pentium 4 in 2001 and were supported in AMD processors with their Opteron and Athlon 64 processors from 2003 onwards.
