It has always been possible to construct tests in XJEase which were conditional on something else having happened, or a previous test having passed, but the new v3.5 release includes a number of major enhancements to the setup, running and control of tests in XJDeveloper and XJRunner, some of which make conditional testing much easier to [...]
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. […]
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 [...]
We’ve made some improvements to the Power/Ground nets screen to make it easier to identify power and ground nets. We recommend that the first thing you do after adding your board is to classify the power and ground nets on the boards. This will improve our ability to correctly suggest categorisations for your devices, in [...]
Transistors are one of the things we get asked about quite a bit: “How should I categorise the transistors in my project?” […]
‘Dynamic Chains’ is a term we’ve coined to describe a test system that has the ability to drive more that 1 JTAG chain configuration. This may be possible if it has multiple chains driven by different TMS or TCK pins, or a single chain that has multiple JTAG device variations (for example using a Scan Bridge). Before v3.3, XJTAG projects [...]
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.
XJTAG is a great system for board designers and manufacturers, but people looking to repair boards often do not have netlists for those boards – something that until now has been essential to start an XJDeveloper project. […]
To help get your tests up and running more quickly and easily, version 2.7 of XJDeveloper has a new feature which can make suggestions for the JTAG chains in your project. […]
