Differential Terminations in XJTAG
This post is to try to clarify what XJTAG understands by the term “differential termination”. […]
Driving differential pins in XJEase
A few people have asked us how to deal with differential pins when writing XJEase tests. They see them change value on an oscilloscope during the Connection Test, but aren’t sure how to deal with them explicitly in .xje files. […]
XJTAG Time and Unix Time
This article is a summary of our answers to various customers who have asked us how to convert between XJTAG, Windows and Unix timestamps, so that they can correctly pass data between test systems. […]
Create your own links to Layout Viewer from XJEase
From version 2.6.2 onwards XJEase supports the printing of device, pin and net links which launch and get highlighted in Layout Viewer from XJRunner and XJDeveloper (provided there is an ODB++ netlist available for the board). […]
The Safe bitstream
The Safe bitstream gets mentioned occasionally in our documentation and warning/error messages and this blog post attempts to shed some light on what it is and what it’s used for. […]
Logic in XJTAG – capabilities and limitations
We see a lot of logic components used on boards that come through our office. Most often we see buffers, bus transceivers and devices of that nature, but also plenty of the usual discrete logic chips – simple gates, decoders, encoders etc. […]
Using XJEase functions in XJRunner tests
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 [...]
Integrating XJTAG with other Test Systems – System calls from XJEase
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. […]
Collecting user input from XJEase
A customer recently asked how to read some input from the user in XJEase. The next major release of XJTAG (probably numbered 2.4) will contain a new XJEase function INPUTBOX that makes doing this much simpler. In the meantime, I thought I might outline some code that accomplishes the same thing in the current version. [...]
XJEase: The SET Statement
In XJEASE the SET statement is the command to access pins via a JTAG device. XJEase works out via the BSDL files and netlist how to access a pin on a non JTAG device from a JTAG device. […]
