OBSERVATIONS

Clearing the air on multiple scan paths
by Dave Bonnett

Seems like more and more designs feature multiple scan paths these days. Sometimes more than one scan path is needed, but often it would be better to have just one because boundary scan is most efficient when there’s only one scan path on a design. Fortunately, when the design has to have multiple scan paths, ScanWorks can lend a very helpful hand.

Simplicity of ScanWorks speeds up HP’s time-to-test

Because Hewlett Packard Printer Division’s test group has several occasional users of JTAG test, the simplicity of the test system’s interface was of paramount importance. The group’s manager thought that the periodic users would be more productive with a system like ScanWorks that is highly graphical and intuitive.

TECH TIP

Sophisticated device modeling is key to optimizing automatic test generation
by Adam Ley

Automatically generating JTAG tests is sometimes a balancing act among the time it takes to develop a test (time-to-test), board safety, and test coverage. Over the years, the algorithms behind ScanWorks’ test generator have continued to improve on how it handles non-boundary-scan device models, to the point where test coverage can be optimized in record time without compromising board safety.

Lead-free solder may shift test methods toward boundary scan
by Dr. Ben Bennetts

The move is on to eliminate pollution-causing lead from the printed circuit board manufacturing process. By 2006, all electronic equipment sold in Europe must be lead-free and the US might not be too far behind. The effects of ‘getting the lead out’ on electronic test and the use of JTAG test techniques will be far reaching.
