We all pay close attention to the termination of high speed signals, especially clock signals. However in many of the designs I see this doesn’t seem to have happened for the JTAG clock signal TCK. But TCK is a clock signal just like any other clock signal.

One of the exciting new features of XJLink2 is the ability to measure a number of voltages. Via the 20-way XJlink2 connector you can measure up to 18 different voltages. This means supply rail voltages can be measured before (and during) JTAG testing, and analogue measurements are now simple to make during your tests.

The new XJlink2 has a button and some LEDs, which aren’t found on most JTAG interface devices. These are simply there to make life a little simpler on a crowded workbench. Once you have a project open in XJRunner you can start testing by just pressing the button – this can be quicker than finding your mouse which has at some point almost certainly moved off the on-screen Run button.

The new XJLink2 USB-to-JTAG interface is beginning to make its way out to our distributors and depending on where you are is, or shortly will be, available for trial and purchase.

A frequent question from customers is, “Why is my new XJEase test function not listed when I create an XJRunner test?”

XJEase Functions

For a function to be eligible to be made available to XJRunner it must be in the main project (.xje) file or a device file, or in a code file specified either in the main project (in the Circuit Code Files Screen) or from within a test device file (in the Test Device Files Screen).

XJAPI is a simple interface that gives low-level access to the JTAG chain via the XJLink. It is intended to allow programmers the ability to integrate the XJTAG hardware into other test systems.

The XJTAG installation includes example projects in C/C++ and C# demonstrating the use of the API. The C# example is easily adapted for use in VB.net if the C# interop wrapper class is compiled into a class library. The examples are installed in the XJTAG Shared Files folder in a folder called ‘XJAPI Examples’. XJTAG installs a shortcut to the XJTAG Shared Files folder in its Start Menu group.

The installation also includes a complete reference for the API.

This series of posts covers how you can integrate XJTAG into your overall test system. This entry focuses on executing programs from within XJEase.

The XJEase keyword SYSTEM is used to execute a system command or program. More »

In XJRunner, the Log File Viewer is a enhanced dialogue which allows you to view XJRunner’s logged output without having to open an external text file viewer.
