XJTAG Blog

Although it has a JTAG port, the TI MSP430 microcontroller is not a boundary scan capable device. Instead of the standard boundary scan registers there is a set of registers that allow the various functions of the device to be accessed and configured. Read the rest of this entry »

In the XJTAG application note “Working with configured Xilinx and Altera devices” the point is made that the way to get the best test coverage is to test with blank devices.

Blanking a device has its own challenges – Read the rest of this entry »

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. Read the rest of this entry »

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. Read the rest of this entry »

I bet most of you haven’t considered how you wire up a bench power supply – you just set the voltage and current limit and off you go.
