We have recently seen Agilex BSDL files that cause XJDeveloper to emit errors looking like this: The cause of this is a mismatch of information. Within the BSDL file, in the Advanced I/O description (AIO) section, there is a section that describes the pins' AC capabilities for IEEE 1149.6 testing. In this section each AC-capable [...]
Our revisions, variants and multi-sourcing features all allow you to use different variations on your root XJDeveloper project, but when is it best to use each one? […]
XJTAG 4.1 introduces enhancements to the ARM Serial Wire Debug (SWD) protocol to return protocol operation acknowledgement responses in XJEase. […]
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: […]
One potential cause of damage to an XJLink2 JTAG controller is transient current spikes caused when a board is first powered on and the decoupling capacitors are charged. We’ve talked about this issue on the blog before and shown that, unfortunately, even a very brief spike in current can cause damage to the controller. [...]
Continuing from XJTAG 3.12’s Enhanced Signal Integrity Analysis feature (see here and here), XJTAG 3.13 brings more algorithms to help identify potential issues with the JTAG chain. This article describes more of the symptoms it can spot and their likely causes. […]
One of the new features in XJTAG 3.13 is an option to speed up the setup of new test device files for I²C devices. […]
On the Variants screen in XJDeveloper, the Variant Details panel displays the selected profiles and current variations for the variant selected in the Variants List. […]
A new major version of XJTAG – version 3.13 – is now available from our website for users who are in maintenance. […]
XJTAG 3.12 has extended the functionality of the Find and Replace dialog that is accessible when viewing XJEase or BSDL code files. […]
