A diff is a comparison showing differences between the contents of files. This article is specifically about displaying the difference between the a project’s current version of an XJEase library file, and the latest version of that file available from the library that it belongs to. […]
With XJTAG 3.11 we’ve made some improvements for working with projects that use the Dynamic Chains feature. Previously, the Analyser, Debug Connection Test, and the Chain Debugger feature would always use the default profile for your project. Using a different profile for these features would require you to manually change the default profile in XJDeveloper. Now, in XJDeveloper, the required profile may be selected independently on each screen, via a drop-down selection menu. […]
In XJTAG 3.11 we’ve added configurable oscillator functionality which can be used on any XJLink2-based controller. The oscillator operates independently of TCK, so can run when TCK is not running and can be set to any frequency from 10 kHz to 166 MHz (in 10 kHz increments) regardless of the current TCK frequency. […]
Historically we have provided three mechanisms for defining some form of constant or default values for a pin/net in XJDeveloper. These are BSDL compliance pins, bus disable values and constant pins, which allow you to define pins which XJTAG should keep in a constant state during automated testing, such as with Connection Test. However these approaches are profile- and subchain-agnostic. […]
The second part in this 2 part series about the new user libraries feature in XJDeveloper 3.11 will explain how user libraries are useful in XJDeveloper. When devices are categorised using library files (as opposed to using files saved on disk) you can re-use these library files in other XJDeveloper projects with ease and all projects can be automatically updated when a file is modified. […]
A Bill Of Materials (BOM) can be added to a board by importing from the netlist, from a suitable schematic file, or from a separate BOM file. […]
A new feature in XJTAG 3.11 is the ability to create user-defined XJEase libraries containing your own XJEase device files and additional code files. Part 1 in this 2 part blog series will explain how to use the new XJEase Library Editor application to create user libraries. Part 2 will then explore how user libraries are used in XJDeveloper. […]
A time-saving feature of XJTAG v3.10 is streamlined background compilation of projects, drastically reducing the startup time to run tests. […]
XJTAG 3.10 adds a control that allows the default values of XJEase global variables to be overridden. In XJDeveloper, clicking on ‘Options’ at the bottom of the test list on the Run Tests screen now includes a Set Global Variables tab: […]
One of the standard types of testing that is done in XJTAG’s Connection Test is to detect stuck-high and stuck-low faults (shorts to power/ground). Using the IEEE 1149.1 JTAG standard this can be done providing the net has full IN/OUT functionality – that is to say it can both drive output and read input at the same time. The test is implemented by driving the net high or low and then checking that the value read from the net changes to reflect the value driven. […]
