With Buzz , you can easily define up to two boundary-scan chains and quickly verify chain integrity. Once the chains have been checked, Buzz provides a sample of the I/Os.

The watch window in Buzz shows you the current logic state of any specified boundary-scan pin on your board. Buzz also gives you a very handy continuity check to see if two pins on your prototype board are connected, essentially the familiar DMM's buzz measurement, but without probes. Within Buzz's Measure window, you select the drive pin, set it high or low, and read the resulting value on the sense pin.

Check for the presence of a pull-up or pull-down by setting the driver to Hi-Z. And, going well beyond the functionality of a DMM, Buzz shows multi-pin nets just as easily. Drive from one pin to many to check for correct fan-out connectivity or from multiple pins to one or more sense pins, thereby creating a simple cluster test.
