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 [...]
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 [...]
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: […]
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. […]
XJTAG 4.1 adds support for the newly released XJLink-PF40, XJTAG’s new test controller. Projects in XJDeveloper can now be set up for use with an XJLink2 or an XJLink-PF40 or both. […]
In XJDeveloper and XJInvestigator, the ways in which you can interact with the list of screens have been improved. […]
XJDeveloper 4.0 now has a brand new modern look to the Boards screen with 3 possible display modes: Tile mode, Row mode and Grid mode. The new interactive tile and row controls dedicate more screen space to each board so the data can be presented in a clearer, more readable display. […]
In previous versions of XJTAG the JTAG chains in the circuit were all operated at the same frequency. Because the Optimised Scans feature in v4.0 now allows a different frequency to be set for each chain, some changes to the user interface were required, and as a result the chain frequency settings in the user [...]
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. […]
XJTAG 3.13 brings with it an updated Debug Connection Test screen in XJDeveloper and XJInvestigator. The screen is primarily used to find problems with the setup which cause the Connection Test to exit with a broken chain error. […]
