概要

This paper first defines the controllability/observability measures and the testability measure at the functional level, based on the gate level testability measure. Next, it describes an effective calculation method for the proposed functional level testability measure and offers an example of a typical functional block calculation. The method is based on a functional block description of a given network, and is easily applicable to various network categories. Finally, the relationships between the proposed functional level testability measure and the test data fault coverage are analyzed using the results of the D-algorithm ATPG program execution for a certain time. It is shown that the functional level testability measure can be used as an effective guideline to improve the testability bottlenecks of digital networks.
