XJTAG 4.2 Release Notes

New features and enhancements

Please see the Change Log for a list of new features and enhancements in XJTAG 4.2.

XJTAG targets .NET 4.8

XJTAG 4.2 targets .NET 4.8 rather than .NET 4.7.1. This change may affect customers in two scenarios.

If you are creating .NET applications that use XJIntegration and targeting .NET 4.7.1, you will need to update your project to target .NET 4.8 to match.
If you are creating external API assemblies to provide additional functionality from XJEase during testing and those assemblies have additional dependencies, you may need to update your projects to target .NET 4.8.

Prompts to update library definitions when opening a project now disabled by default

When XJDeveloper opens a project that uses test device or passive device definitions that have been updated, it prompts to update these files from the library. In v4.2, this behaviour has been disabled by default, but can be re-enabled via a new checkbox in the Options dialog.

Supported Platforms

XJTAG recommends using the Windows 11 operating system, and is supported on all Intel x64 builds of Windows 11.

XJTAG will run on both the 32- and 64-bit Intel processor variants of the following obsolete operating systems: Windows 7^® Service Pack 1, Windows 8.1^® and Windows 10^® 1607 (Anniversary Update) and later. However in Windows 7 and Windows 8.1 some minor UI functionality is missing and XJTAG may not be able to fully support running on these operating systems. XJTAG makes no guarantee that future updates to XJTAG will run on these operating systems.

This version does not support Windows XP, Windows Vista, Windows 8 or Windows 10 1507 or 1511 (November Update).

XJTAG does not currently run on PCs with Arm processors.

XJTAG recommends a screen resolution of 1920×1080 or higher.

Target Hardware

In order for XJTAG to interact with a circuit, the JTAG chain must be set up properly. To help with this, we have a produced a set of DFT guidelines, available from the XJTAG website. There is also a troubleshooting section in the help files.

Side-by-side installations

It is only possible to have one instance of each major release of XJTAG installed. It is possible, for example, to install any variant of version 3.4.x along side any variant of version 3.5.y; however it is not possible to install two variants of version 3.4, e.g. 3.4.3 and 3.4.4.

Changing Project File Associations

By default, double-clicking on an XJTAG project file of any kind will open it in the most recently installed version of XJTAG. The Version Check utility (XJVersion) can be used to control these file associations. It is recommended to do this using the copy installed with the latest version of XJTAG that you have installed.
