Building Buses
File
Specifies the file designator for the source history file. File designators
are selected from the pull down menu next to the File field. As you
switch files, the Bus Builder dialog lists only the buses associated
with the selected file. You can not drag a component from one file into
a bus created from another file.
Scope
When a bus is created, it is associated with a scope in the design.
The bus will be displayed in the Hierarchy Browser Signal Select pane
for its associated scope. The Scope field allows you to modify the
default scope. The default scope is determined by the following:
If all components are from the same scope, that is the default
scope.
If all components have a common ancestor, the scope is that
ancestor.
If there are no common ancestors, the scope will be the root scope.
Ascending/Descending
Specifies whether the bits are numbered in ascending order (0-5) or
descending order (5-0).
Bit Range
By default the bit range is 0 to N. You may edit these values.
Invert
Inverts each data bit in the bus. For example, 4’b1010 inverted would
become 4’b0101.
