Terminations to a reference voltage in XJTAG
This post is to clarify how to specify terminations to a reference voltage in XJTAG. There are two special classes of passive device in XJTAG which represent termination resistors. […]
1149.6 testing in XJTAG
1149.6 testing is coming of age, and though XJTAG has supported IEEE Std. 1149.6 since software version 2.1 (released in 2008) it seems to us that 1149.6 devices are becoming much more common in the last couple of years. […]
Layout Viewer Visualisation
Having lots of information is great, but sometimes the most difficult thing is displaying that data in a meaningful way. We have created two new information overlays for Layout Viewer, allowing you to visualise test coverage statistics or live pin data from Analyser on your board layout. […]
Introducing Dynamic Chains
‘Dynamic Chains’ is a term we’ve coined to describe a test system that has the ability to drive more that 1 JTAG chain configuration. This may be possible if it has multiple chains driven by different TMS or TCK pins, or a single chain that has multiple JTAG device variations (for example using a Scan Bridge). Before v3.3, XJTAG projects could only represent a single static JTAG chain. With our new functionality, multiple JTAG chain variations can be defined, set up and run within a single XJTAG project in a single test run. […]
Using XJTAG without netlists
XJTAG is a great system for board designers and manufacturers, but people looking to repair boards often do not have netlists for those boards – something that until now has been essential to start an XJDeveloper project. […]
XJTAG version 3.2
A new major version of XJTAG – version 3.2 – is now available from our website for users who are in maintenance. […]
Triggering code when tests complete
In Version 3.0.2 and later an additional Settings tab has been added to the XJRunner Setup screen in XJDeveloper. This tab, labelled “Functions”, […]
XJTAG version 3.1
A new major version of XJTAG – version 3.1 – is now available from our website for users who are in maintenance. […]
XJTAG 2.7: Improved code editors
We are always listening to customers about where they feel the tools could be improved. For XJTAG 2.7 we took this feedback on board and improved the user interface of the code editors in XJDeveloper. These are on the Test Device Files screen and the Circuit Code Files screen. […]
Schematic Viewer
From version 2.7 onwards XJTAG includes an integrated Schematic Viewer in XJDeveloper and XJRunner. If you have your boards’ schematics in PDF format you can take advantage of this new feature. […]
