XJEase Call Stack
From XJTAG version 3.6, the XJEase debugger in XJDeveloper now comes with a Call Stack window providing more information about the XJEase code being executed. […]
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 [...]
Categorising devices: Ignore, Unfitted, or Uncategorised?
(This article has now been replaced by an updated version, here.) […]
Input parameters for test functions
Until now, XJRunner tests have been limited to functions which have no input arguments and a single return argument (which returns the result). XJTAG v3.5 relaxes that restriction, allowing input in XJRunner tests, though there is still a requirement to have a single return argument for the result. […]
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 [...]
Conditional testing in XJRunner
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 [...]
New XJEase library available
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. […]
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 [...]
Errors and Warnings pane improvements
In version 3.4 of XJTAG we have aimed to improve the usefulness of the Errors and Warnings panes by adding a number of new ways to interact with errors and warnings. When you have errors or warnings in your project, it sometimes isn’t immediately obvious what the cause is or where they can be fixed. [...]
