XJEase SWD Enhancements
XJTAG 4.1 introduces enhancements to the ARM Serial Wire Debug (SWD) protocol to return protocol operation acknowledgement responses in XJEase. […]
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. […]
XJDeveloper support for XJLink-PF40
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. […]
DDR5 support in XJTAG
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 [...]
XJPack files in JTAG Chain Debugger
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 [...]
Test Reset Sequence Editor Improvements
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. […]
New display modes on the Boards Screen
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
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. […]
