JTAG Pin Restrictions
One of the new features in XJDeveloper 4.2 allows you to limit the capabilities of individual JTAG-capable pins by applying Do Not Read, Do Not Drive and Do Not Read or Drive restrictions. Previously this kind of change would require you to edit the BSDL file, now such restrictions can be included as part of your [...]

Tips for setting up an XJLink-PF40 pin mapping
With the release of the XJLink-PF40 and XJTAG 4.1, setting up your pin mapping might have just got a bit more complicated. The XJLink-PF40 supports twice as many TAPs (8) and has twice as many I/O pins (40) as the XJLink2 so there can be more work involved in setup. Luckily, XJDeveloper 4.1 contains some [...]
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: […]
Multi-sourcing Device Configurations
New in version 4.1, XJTAG has support for multi-sourcing test device configurations. This post will explain how to define multiple possible configurations for your test devices. A follow-up post will compare XJTAG’s Variants, Revisions and Multi-sourcing features and explain which is best to use in different scenarios. […]
