Using CONNECT vs PULL in PDD files
Why use CONNECT not PULL for low-value pull resistors? When a resistor is specified as a pull resistor the XJTAG system will expect two things: […]
XJTAG Boundary Scan Testing with OMAP 35xx devices
Texas Instruments’ OMAP processors are becoming more and more popular. We have seen quite a few come through the office recently. The good news is that the OMAP processors do support boundary scan testing. […]
Debugging faults: always remember XJAnalyser!
The traditional technique for debugging printed circuit boards is to “observe” the state using oscilloscopes or multi-meters and deduce a fault. This method actually suppresses a very powerful engineering instinct that would help us a lot if we could only give it a better chance. […]
Debugging the Connection Test – part 4 (Logic errors)
With the new Logic support in XJTAG, the connection test can find more errors […]
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. […]
Highlights of the 2.4 Release
The latest version of XJTAG, version 2.4, is now available to customers who are in maintenance. […]
New XJTAG contact details
XJTAG has moved office. Our office move is complete and all our details are now updated on the XJTAG website, but just to make sure everyone has picked up our new contact details, here they are. […]
XJLink2 Diagnostics
XJlink2 comes with a detailed self test program. Accessed via the “Test…” button in XJLinkManager this enables you to run a diagnostic report on your XJlink2. […]
XJLink2 button and LEDs
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. […]
Debugging Connection Test – part 3
Solving common Connection Test problems There are several types of error found by Connection Test which regularly (and unsurprisingly) confuse users. This article tries to help out… […]
