The methods you can use to name a net, are described in the table below.

Net Naming Method Description
Auto-naming When a net is created, it is assigned an automatic net name by the system. These names are unique in the design and take the form of numbers.
Assigning a preferred net name You may assign your own name to a net by entering a name in the Preferred net name field in the Net name tab of the Net Properties dialog box.
Connecting to global connectors Attaching global connectors to nets creates a global net. The net inherits the name of the global connector and becomes available throughout the design.
Connecting to the ground symbol The analog ground connector
is a special case of global connector. Any net connected to it is named 0. You cannot edit this name.
Connecting to on-page connectors A net may also inherit the name of an attached on-page connector. Use on-page connectors to virtually connect two nets on a schematic page.
Connecting to off-page connectors Nets connected to an off-page connector may inherit the name of the off-page connector.
Connecting to hierarchical/subcircuit block connectors

Nets connected to a hierarchical connector may inherit the name of the hierarchical connector.

Net naming becomes more complex when designs contain global nets, connectors, or subcircuits and hierarchical blocks.

  Each naming method has a priority level.
