Please see the Change Log for a list of new features and enhancements in XJTAG 3.8.
XJTAG 3.8 includes a new Layout Viewer for viewing ODB++ data. One consequence of this is that the way ODB++ data is included inside XJPack files has had to be changed; XJPack files created in XJTAG 3.8 will now be significantly smaller, but the layout data will be unavailable when running in an older version.
The :=* operator in XJEase allows a bus to be read while it is still outputting. Previous versions of XJTAG erroneously allowed a space to be put between the := and the *. This is no longer allowed.
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®.
This version does not support Windows XP or Windows Vista.
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.
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 set of DFT guidelines. There is also a troubleshooting section in the help files.
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.
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.
