6.4 Buses
In order to simplify wiring, buses may be used to carry multiple nets. Buses may be used
within a page, across pages, and down into nested circuits (subcircuits and hierarchical
blocks).
Buses operate in two modes. In net mode, a bus is simply a collection of nets. Each time a
wire is connected to a bus via a bus entry, you are given the choice of connecting that new
wire to an existing net already in the bus, or of adding that net to the bus.
In busline mode, you may pre-define the number and names of buslines that are contained in
that bus. When connecting a wire to the bus via a bus entry, you are prompted to specify
which of the existing buslines the new wire should attach to. All wires attached to the same
busline are merged into the same net.
Note The bus wiring mode is set in the
Wiring tab of the Sheet Properties dialog box. See
3.4.2.3 Sheet Properties - Wiring Tab on page 3-27.
