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: […]
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. […]
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. […]
Here is a summary of the additions to the XJEase library made recently in library version 183. Note: Some files in this library require an XJTAG software version of at least 3.10.6. […]
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. […]
XJTAG has included partial support for the standardised PCOLA/SOQ method of measuring test coverage for some time. The recent XJEase library update, library version 181, contains PCOLA/SOQ data for the test coverage of devices, completing this functionality. […]
In XJDeveloper and XJInvestigator, the ways in which you can interact with the list of screens have been improved. […]
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. […]
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 [...]
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. […]
