Boundary-Scan Interconnect Diagnosis explains how to synthesize
digital diagnostic sequences for wire interconnects using boundary-scan,
and how to assess the quality of those sequences. Its importance has to
do with designing complex electronic systems using pre-designed
intellectual property (IP) cores, which is becoming increasingly popular
nowadays. Since tests for pre-designed cores can be supplied with the
cores themselves, the only additional tests that need to be developed to
test and diagnose the entire system are those for wire interconnects
between the cores.
Besides the trivial solutions that are often used to solve this problem,
there are many more methods that enable significant optimizations of
test vector length and/or diagnostic resolution. The book surveys all
existing methods of this kind and proposes new ones. In the new approach
circuit and interconnect faults are carefully modeled, and graph
techniques are applied to solve the problem. The original feature of the
new method is the fact that it can be adjusted to provide shorter test
sequences and/or greater diagnostic resolution. The effectiveness of
existing and proposed methods is then evaluated using real electronic
assemblies and published statistical data for an actual manufacturing
process from HP.
