The Study Unused Output Functions List identifies all unused functions in the given hierarchical design. This report will only list unused output functions in design levels contained within the current hierarchical expansion. Because, in eXpress analyses, unused functions are not considered part of the system design (and are therefore not taken into consideration when calculating metrics such as system probability of fault detection), it is
extremely important that the analyst verify that the list contains no lower-level output functions that actually should be represented as participating in the overall system functionality.
Report Content
The Study Unused Output Functions List consists of a single table similar to the one depicted below:
Study Unused Output Functions List

7

This table is comprised of the following five columns:
## column - this column sequentially numbers the lower-level, unused functions that are listed in the report. The last entry in this column thus specifies the total number of unused functions in the levels of thehierarchical design defined by the hierarchical expansion.
Object (Port) - this column lists the object and port for which the given output function has been defined. When the object exists in a design other than the top-level design, then a design prefix (colored blue) is prepended to the object (colored black) and the port (light blue) names. The port abbreviation, object abbreviation and prefix (when included) are all Hotlinked to the design containing the function.Click on the prefix to load the design file (if necessary) and then click on the object or port abbreviation to locate the selected element centered in the design window.
