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. […]
In previous versions of XJTAG the JTAG chains in the circuit were all operated at the same frequency. Because the Optimised Scans feature in v4.0 now allows a different frequency to be set for each chain, some changes to the user interface were required, and as a result the chain frequency settings in the user [...]
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 3.12 expanded the capability of the Signal Integrity Analysis in XJTAG tools, adding the ability to suggest certain causes of error. This post continues from the previous post on this subject, and describes further errors that XJTAG tries to identify. […]
