Windows 10 support
Microsoft is ending mainstream support for Windows 10 on October 14th, 2025. This means that after this date updates to fix security issues will not generally be available and so machines running Windows 10 will be more vulnerable to security risks and viruses. […]
Built-in Test Reset Sequences for devices with nTRST pins
XJTAG 4.1 can automatically generate test reset sequences for many more hardware designs than previous versions. Previously, if a JTAG device had an nTRST pin that needed resetting between tests, you had to manually create a sequence with a waveform like the following: […]
Test Reset Sequence Editor Improvements
XJTAG 4.0 has significantly improved the user experience of creating and editing test reset sequences – the way in which JTAG devices are put into their JTAG mode. […]
Switching Screens in XJDeveloper and XJInvestigator
In XJDeveloper and XJInvestigator, the ways in which you can interact with the list of screens have been improved. […]
Setting TCK frequency
In previous versions of XJTAG the JTAG chains in the circuit were all operated at the same frequency. Because the Optimised Scans feature in v4.0 now allows a different frequency to be set for each chain, some changes to the user interface were required, and as a result the chain frequency settings in the user [...]
Improvements to the Debug Connection Test Screen
XJTAG 3.13 brings with it an updated Debug Connection Test screen in XJDeveloper and XJInvestigator. The screen is primarily used to find problems with the setup which cause the Connection Test to exit with a broken chain error. […]
Variants Part 5 – Export Options
XJDeveloper provides a couple of options for exporting variants in XJPack files or as stand-alone XJDeveloper projects. When exporting a project with variants to an XJPack file, a Variants tab is displayed in the XJPack Dialog. This tab allows you to select any combination of the root project and variants to include in the file. [...]
Variants Part 4 – Setting Up the Test List
So, you’ve set up your variants with all the right BOM data and categorised all the devices (perhaps using the Suggest Variations wizard), now you need to actually test them! […]
XJPack file privilege settings
In XJTAG 3.12, from XJDeveloper, you can now define the level of access that XJRunner/XJInvestigator users have to features of your packed project, using the XJPack file settings. Disabling a feature will override any user privileges the XJRunner user may have (e.g. disabling editing the test list would disable this for all users in XJRunner, [...]
