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 [...]
XJEase Debugger
An interactive XJEase debugger was added in XJTAG 3.2. This can be used to help find problems in your XJEase code. […]
XJTAG version 3.2
A new major version of XJTAG – version 3.2 – is now available from our website for users who are in maintenance. […]
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. […]
