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 [...]

Terminations to a reference voltage in XJTAG

This post is to clarify how to specify terminations to a reference voltage in XJTAG. There are two special classes of passive device in XJTAG which represent termination resistors. […]

Introducing Dynamic Chains

‘Dynamic Chains’ is a term we’ve coined to describe a test system that has the ability to drive more that 1 JTAG chain configuration. This may be possible if it has multiple chains driven by different TMS or TCK pins, or a single chain that has multiple JTAG device variations (for example using a Scan Bridge). Before v3.3, XJTAG projects could only represent a single static JTAG chain. With our new functionality, multiple JTAG chain variations can be defined, set up and run within a single XJTAG project in a single test run. […]
