Input parameters for test functions

Until now, XJRunner tests have been limited to functions which have no input arguments and a single return argument (which returns the result). XJTAG v3.5 relaxes that restriction, allowing input in XJRunner tests, though there is still a requirement to have a single return argument for the result. […]

Specifying bus access during XJRunner tests

Alongside other improvements to the XJRunner test setup, XJTAG v3.5 has a new interface to specify bus access from the test system using the XJRunner Setup screen. When you edit a test there is now a Bus Access tab on the dialog, which allows full control of which pins are used to read and/or write from a bus during the test. […]

Conditional testing in XJRunner

It has always been possible to construct tests in XJEase which were conditional on something else having happened, or a previous test having passed, but the new v3.5 release includes a number of major enhancements to the setup, running and control of tests in XJDeveloper and XJRunner, some of which make conditional testing much easier to setup, control and debug. […]

Short circuiting logical operators in XJEase

A boolean expression in XJEase is an expression that is considered to evaluate to either false or true. Boolean values are represented by an integer, where 0 is false and any other value is considered to be true. The standard Globals.xje that is included in all new projects has two constants defined, FALSE and TRUE. In XJEase we have three logical operators: NOT represented by !, AND represented by &&, and OR represented by || that operate on boolean values. […]

Common errors when updating files with the new XJEase Library

With the new XJEase Library we have made some fairly extensive changes to reduce code duplication, to improve test coverage, and ease of use.  If you have used additional code files from the XJEase library to create your own test scripts you may find that updating to the new versions of these files causes errors in your project.  Below are the common errors you might see and how to fix them. […]

DDR4 support in XJTAG

We have been starting to see questions about support for DDR4 SDRAM devices, which are gradually becoming available. We have published a guide to using JTAG to test DDR4 memory on the XJTAG website. It contains a link to slides used at a recent presentation on the subject. Support for DDR4 devices will be coming soon [...]
