First, in the 'Manage Models' dialog
box under the 'Tools' pull-down menu, maintenance customers
find several selections, including the web library called
"Models on the Web." The second new web library
is under the "Help" pull-down tab and it is
called "ScanWorks on the Internet."
The "Models on the Web" library
is made up of device models that can be used to streamline
test development. Instead of manually characterizing
a device on a boundary scan test chain, a device model
can simply be dropped into the test, significantly reducing
the time and effort involved in test development. Many
of these models have been created by ASSET support personnel,
other ScanWorks users and several of ASSET's strategic
partners, such as Agilent Technologies.
"The model library is growing
all the time," said Arden Bjerkeli, ASSET's Director
of Customer Application Support. "Agilent has supplied
quite a few models from it 3070 ICT device library and
our support people are constantly writing new models.
We always encourage users to share the models they've
developed. The ScanWorks community is building up a
considerable amount of shared resources."
The ScanWorks "Models on the
Web" library is composed of four kinds of files,
including models for flash memory devices, memory devices,
non-boundary scan devices (cluster models) and BSDL
(boundary scan description language) files. Customers
can use an automatic search function to find a model
or BSDL file for a particular device. Before downloading
the model, the viewer can review information about the
file, such as who created it and how the accuracy of
the file was tested. In addition, the content of the
model can be reviewed before it is downloaded.
The other web library, which is located
under ScanWorks' "Help" tab, is accessed through
a selection called "ScanWorks on the Internet."
This takes the customer to a special web site called
"ScanWorks Maintenance Benefits." Here, several
benefits are available, including software updates and
service packs. Customers can select one of these items
and it will be downloaded and automatically installed.
In addition, the "ScanWorks Maintenance
Benefits" web page also offers application notes,
design-for-test advice and tips for engineers and technicians,
and an interactive user message board. The applications
notes have been written by ASSET's support personnel
and users. The standards tips section of the web site
features advice on how best to implement boundary scan
in conformance with the pertinent standards. ASSET has
compiled a number of useful documents, which can be
accessed from this page, including a "Boundary
Scan Tutorial," "Guidelines for Board DFT
(Design-for-Test) Based on Boundary Scan," "Boundary-Scan
Board-Level Testability Checklist" and others.
The last item on the "ScanWorks
Maintenance Benefits" web site is a ScanWorks user
message board, which will be activated during the second
quarter of this year. Through this facility, ScanWorks
customers will be able to exchange insights and observations
with each other to derive as much value as possible
from the many capabilities of boundary scan in general
and ScanWorks in particular.
