We are starting to see an increased number of questions about support for DDR5 DIMMs and SDRAM devices, which are rapidly becoming mainstream. Support for DDR5 devices will be added to the XJEase Library in the near future, but in the meantime XJTAG can now make DDR5 models available on request to customers with a [...]
XJTAG 4.0 introduced Optimised Scans, providing more options for configuring JTAG chains and improving scan speeds. To assist debugging any problems getting chains to run when deploying projects using these new features into a production environment, JTAG Chain debugger has also been given an update: if run in a system with an XJRunner licence, the [...]
XJTAG 4.0 has significantly improved the user experience of creating and editing test reset sequences – the way in which JTAG devices are put into their JTAG mode. […]
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. […]
Optimised scans is a new feature added to XJTAG 4.0 and it provides a number of improvements aimed at increasing test speed. With Optimised Scans enabled, every JTAG TAP will scan data through at a separate frequency based on the capabilities of the JTAG devices in that TAP group. […]
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. […]
XJDeveloper provides a couple of options for exporting variants in XJPack files or as stand-alone XJDeveloper projects. When exporting a project with variants to an XJPack file, a Variants tab is displayed in the XJPack Dialog. This tab allows you to select any combination of the root project and variants to include in the file. [...]
So, you’ve set up your variants with all the right BOM data and categorised all the devices (perhaps using the Suggest Variations wizard), now you need to actually test them! […]
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. […]
