Because the eXpress software uses internal IDs to uniquely identify different design elements, it is easily able to distinguish between similar elements that are either unnamed or have been assigned the same name. There are a few cases, however, where the specific name that is assigned to an entity can have an effect upon the analyses produced by the design.
Output Function Names - when output functions on multiple ports of an object are assigned the same name, they are considered to be the same function (for a more in-depth discussion of this, see the discussion of Duplicate Function Names).
Port Names on Components - when multiple ports on a component are assigned the same name, the default output function names will be the same as well (see the previous entry in this list for a description of the consequences of this). If this is not desirable, the Analyst should either assign different names to the ports or explicitly assign unique function names. For more information on this topic, refer to the discussion of Duplicate Port Names.
Port Names on Assemblies - when an object is converted into an assembly using the top-down approach to hierarchy, the port names on the upper-level object must initally correspond to the names of the I/O flags within the lower-level design (this is not an issue for bottom-up linking).
I/O Flag Names - when multiple I/O flags are assigned the same name within a single design, they are considered to represent the same signal coming into or out of the design (only a single port will be used on an assembly linked to this design).
Try to use Abbreviations on IO flags to keep flag naming short and use the description field to amplify IO usage. If the flag name is the same at both the source and destination, Interconnection can be achieved automatically at the next level up. Use of Color on IO flags is strongly recommended to distiquish signal types and the Color Legend should be filled out. For a "Test Point flag", Interpretation [Context Panel] should be set to "Provide I/O only within current design"
Typical Flag types - Communication, Power, Fluids, Digital Inputs, Digital Outputs, Bidirectional signals (buses),
Test Location flags - Fireware, Software,Test Points, LEDs, Gauges
