Corelis’ Boundary-Scan Technology Facilitates Applied Data
Systems’ Customization of Embedded Systems
Streamlines ISO 9001 Certification
Applied Data Systems
(www.applieddata.net)
is the leading supplier of “application-ready” RISC-based single
board embedded systems with flat panel displays for customers
who need XScale or StrongARM-based systems running Windows CE,
Linux or the operating system of choice. Nearly half of the
company’s customer production designs are completely customized.
“We call ourselves a
delicatessen,” jokes Bob Olsen, president of the company,
“because we try to accommodate every customer’s preferences.”
As the company’s product family
grew over the past three years, the configurations of board
designs became so numerous that tracking and programming
those designs became inefficient, time consuming, and very
expensive. Looking into different alternatives to solve
their problems, ADS decided to apply boundary-scan
technology for testing and in-system programming.
Anthony Mallon, an ADS Lead
Test Engineer, was tasked with evaluating boundary-scan
tools. Anthony started by comparing several different
systems. He was impressed with Corelis in the evaluation
cycle because of their highly-automated products and because
Corelis staff was willing to help ADS to evaluate the
Corelis products on ADS’ own products, not just on their
evaluation board. In fact, Anthony was more impressed with
the Corelis team’s ability to get everything up and running
over the phone than a competitor’s ability to demonstrate
their package in person.
Although originally planned for
in-system programming, Anthony soon learned that full
interconnect testing was very fast and thorough at
pinpointing faults and isolating problems. Anthony’s
team found that ScanPlus is a great test and diagnostic
tool, allowing them to quickly isolate the source of the
problem and providing immediate ‘pin-level’ diagnostics.
Corelis’ ScanPlus tools now
allow ADS test engineers to perform testing and in-system
programming with minimal effort. For Anthony, this means
more synchronization between his own product tests and the
tests done by ADS’ contract manufacturing off-site. “Because the ScanPlus tool is
automated, it is preventing configuration errors and eliminating
human errors,” explained Anthony. “During our prototype stage,
we can streamline to production more effectively, and our
initial testing involves less ‘stop-and-start’ checking by the
entire engineering team.”
Anthony has since pushed Corelis
ScanPlus tools even further by designing his own test fixture
allowing testing and in-system programming of 4 boards
simultaneously with the Corelis ScanTAP-4 module. He
included extra boundary-scan logic on the fixture to test the
connector interfaces on the target boards.
“Once the Corelis unit was here,
we’re finding more uses than the original justification,”
explained Anthony. “Our engineers are coming back to the
testing area with miscellaneous testing requests that are very
easy to do now. We were not able to do these miscellaneous
projects as smoothly and easily before. The Corelis ScanPlus
system has become invaluable for us, especially with all of our
custom work and designs. Unusual problems become irrelevant
because the Corelis system easily compensates for these unusual
configurations making testing simple. We have been very pleased
with the Corelis system. It has delivered even more than we
expected.”
Applied Data Systems recently went
through their ISO 9001 certification, and the Corelis testing
was very beneficial throughout the entire process. Anthony was
able to test the entire ISO process, one system at a time in a
more accurate way.

“We
were very pleased that the Corelis package did exactly what
it claimed it would, The Corelis team knew their product
very thoroughly and knew how to get us up and running
quickly.”
