Self-Diagnosis Of Electronics With Analog Circuits
- Developmental Concepts
by Dennis L. Feucht

Having set forth a strategy for electronic product self-test, including
built-in diagnostic capabilities, in the Introductory
Concepts TechNote, this subsequent TechNote continues by formulating
the next level of development detail.
The previous knowledge-based diagnostician (KBD) architecture showed four conceptual levels of abstraction, corresponding to four progressive self-test products. Each hierarchically-higher level is a superset of the lower ones, and builds upon them. Consequently, a product development path for embedded self-diagnostics begins at the lowest and conceptually most concrete level and expands upwards. These levels are necessary to manage conceptual complexity through modular construction of successively greater functional levels.
