XJTAG’s extension for Altium Designer is now available! It is called the XJTAG DFT Assistant and is aimed at board designers who want to improve the testability of their designs through boundary scan. […]
When using JTAG with a Device Under Test (DUT) connected to a bed-of-nails test fixture, often little attention is paid to the way the JTAG signals are wired. This article (published in SMT magazine last year) gives a helpful explanation of why it is important to get this right, and gives tips for best practice.
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. […]
Many of us have been designing electronics for years and haven’t really considered pull up and down resistor values. We just use the same old values like 10K. With some new silicon the leakage currents are higher than we have been used too. This means the pull resistors might not being doing the task we require. When there is a need to reduce power consumption, again these values need to be looked at in greater detail. XJTAG often finds resistors on boards that don’t actually perform the task intended. […]
