Highways

A highway represents multiple signals in a single graphical representation.

Note

Highways are also known as tramways and raceways.

A highway appears both graphically in a diagram and under a Highways node in the Design Browser Window, under which the signal interfaces interfacing with it are listed.

When filtering is applied to a diagram, a highway is filtered out if all signals interfacing with it are filtered out.

When highway functionality is described in this document, the word “termination” is used to describe a signal termination with an object other than the highway. The word “interface” is used to describe the connection point between the highway and a signal instance.

A highway can have multiple instances within a design or in another design (making the highway a Design Wide Object). If you want to create a highway connection between designs, then you can share a highway to achieve this. In either case, cross-references are supported as on other diagram objects (see Cross-References on Objects) and you can use the View Related Items functionality to view other instances (see Viewing Another Instance of an Object).

If you copy and paste a highway on its own, you will create a new highway (not another instance of the same highway) and no interfacing signals are copied with it. See “Copying and Pasting an Object in a Diagram” in the Capital Design Tools - Common Functions User Guide. Similarly, if you move a highway on its own, no interfacing signals are moved with it.
