Cambridge, England, May 29, 2024 — XJTAG®, a leader in JTAG boundary scan products, has released version 4.0 of its software suite, bringing speed increases both from streamlining the user interface and from increasing throughput of the JTAG chains under test. This new version is all about improving speed and efficiency both for the engineers setting up projects and the production line operator running tests.
The headline new feature is the improved multi-TAP performance provided by Optimised Scans. Multi-TAP refers to the XJLink2 controller’s long-standing ability to operate multiple JTAG chains concurrently, in order to run a test across the whole circuit. In XJTAG 4.0, different chains can now be run at different clock speeds, allowing each scan to be loaded more efficiently by ensuring that a slow chain doesn’t limit the data transfer of a faster one. Whilst the devices on the separate chains will still execute each test step in sync, transferring data through the chains is now optimised, improving test times significantly.
Changes have been made to the look and feel of the products to follow modern design styles and streamline the suite, improving ease of use. These include:
- XJRunner now allows the output of multiple connected XJLink2 or XJQuad controllers to be shown side-by-side simultaneously, allowing tests in a production system to be parallelised more effectively.
- XJDeveloper has had a full refresh, making incremental improvements throughout, including making the Boards screen layout easier to use and adding automatic set up of separate JTAG chains to make the most of the multi-TAP improvements.
- XJAnalyser can now show independent JTAG chains simultaneously, giving a more intuitive representation of the board setup.
- JTAG Chain Debugger has seen significant improvements to the Test Reset Sequence editor. Following feedback, we have made this interface much more intuitive and fluent to use, allowing the waveforms to be more easily manipulated.

About Boundary Scan
JTAG is an IEEE standard that was developed to address the difficulties of testing circuits that use packaging technologies such as Ball Grid Arrays and Chip Scale Packages, where solder connections aren’t accessible. Although JTAG has since become popular for processor debug and for programming FPGAs and CPLDs, they only make use of the standard’s communications protocol. The full benefit of the JTAG standard comes through using boundary scan techniques for testing and debugging assembled boards; XJTAG’s tools give you an easy way to use those capabilities.
