Supported Platforms

XJTAG is supported on both the 32 and 64 bit variants of the following operating systems: Windows 7® Service Pack 1, Windows 8®, Windows 8.1® and Windows 10® 1607 (Anniversary Update) and later.

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

XJTAG recommends a screen resolution of at least 1024×768.

XJTAG requires a processor that supports the SSE2 instruction set. This includes every Intel processor since the Pentium 4 and every AMD processor produced since the end of 2003. See this blog post for more details. This requirement was introduced in version 3.1.

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. 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.
