scope:

This standard defines test features to be included in a mixed-signal (analog and digital) component, together with associated test protocols, to provide standardized approaches to

- Interconnect test: Testing for opens and shorts among the interconnections in a PCA;

- Parametric test: Making analog characterization measurements, and testing for presence and value of discrete components in a PCA; and

- Internal test: Testing the internal circuitry of the mixed-signal component itself regardless of whether it is part of a PCA.

The standard does not mandate implementation details of the test circuitry, although examples of conformant implementations are given for illustration.
