Debugging Connection Test – part 1 (Updated)
This post is an update to the original “Debugging Connection Test (part 1)” post – over time several features in XJTAG have changed considerably and may be hard to find by following my original post. […]
Why categorise resistors, inductors, links and fuses?
Recently one of our newer customers started on their first solo board setup. They had previously seen XJTAG demonstrated and had also had their initial board setup done by an XJTAG engineer. When they came to setting a board up for themselves they tried to follow the path that the XJTAG engineer had talked them [...]
Categorising Transistors in XJDeveloper
Transistors are one of the things we get asked about quite a bit: “How should I categorise the transistors in my project?” […]
1149.6 testing in XJTAG
1149.6 testing is coming of age, and though XJTAG has supported IEEE Std. 1149.6 since software version 2.1 (released in 2008) it seems to us that 1149.6 devices are becoming much more common in the last couple of years. […]
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 [...]
Using XJTAG without netlists
XJTAG is a great system for board designers and manufacturers, but people looking to repair boards often do not have netlists for those boards – something that until now has been essential to start an XJDeveloper project. […]
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. […]
XJEase Editor Improvements in v3.1
The XJEase editors in XJDeveloper are now more intelligent – allowing you to write and navigate around your XJEase code faster. […]
