XJTAG 4.3 Release brings FTDI Support – Faster Setup with Less Hardware

July 02, 2026

Version 4.3 of the XJTAG software suite has added support for FTDI’s JTAG controller hardware. Using FTDI devices, compatible boards can be connected directly via USB, giving full JTAG control and boundary scan testing without the need for an XJLink JTAG controller (so long as there is only one JTAG chain on the UUT).

Since many FPGA and CPU manufacturers are now fitting FTDI devices to their development boards for configuration and debug, having this support gives a quick way for engineers to get XJTAG running on new designs without requiring an XJLink. This also extends into production boards with FTDI devices fitted, allowing rapid programming and testing right on the production line with no external JTAG controller required.

Recent XJTAG updates

In addition to FTDI device support, we've continued to develop the software with regular feature updates, usability improvements and bug fixes, which include:

  • PF-Series controller support now also in XJAnalyser and Chain Debugger (4.3.0)

  • Seica flying-probe machines support added (4.2.6)

  • Manual BGA Device support improvements (4.2.4–4.2.6)
    – easier modelling of unsupported devices

  • Pin Restrictions dialog – enhanced control of JTAG pin usage (4.2.4)

  • Suggestions Wizard workflow improvements (4.2.3–4.2.6)
    – helping reduce the time required to categorise devices and create new projects.

  • Expanded ‘Follow-In’ navigation throughout XJDeveloper (4.2.2–4.2.4)

  • Performance, stability & reliability improvements across all test suite applications (4.2.3–4.2.6)

  • Multi-sourcing added (4.2.0)

  • Online help (4.2.0)

XJEase Library 199–200

The XJEase Library has also continued to evolve, improving on existing tests and further reducing device categorisation and test setup time with support for:

- 1277 new parts
- 18 new XJEase files
- FRAM, NVRAM and ADI SPI devices
- Bug fixes and enhancements for LPDDR4/5, SPI NOR Flash tests, and Common ADC code

XJFlash (2.2.0-2.3.0)

XJFlash adds high-speed programming of flash connected to AMD Versal™ and Versal™ Gen 2 device families (AI Core, AI Edge, Prime, Premium, HBM, and RF series), and Spartan™ UltraScale+™ devices.

Staying Current

If you have an active maintenance contract, we recommend upgrading to XJTAG 4.3 to take advantage of the latest functionality, stability improvements and expanded device support.
