With the release of the XJLink-PF40 and XJTAG 4.1, setting up your pin mapping might have just got a bit more complicated. The XJLink-PF40 supports twice as many TAPs (8) and has twice as many I/O pins (40) as the XJLink2 so there can be more work involved in setup. Luckily, XJDeveloper 4.1 contains some [...]
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. […]
A new version of XJTAG – version 4.1 – has been released, containing updates and new features. It is now available from our website for users who are in maintenance. […]
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 XJTAG 4.0, you are now able to rearrange the tabs in XJRunner so that you can see output from multiple XJLinks at once. The tabs also display more information about the corresponding XJLink than in previous versions of XJTAG. […]
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. […]
A new version of XJTAG – version 4.0 – has been released, containing major updates and new features. It is now available from our website for users who are in maintenance. […]
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. […]
