I’ve been trying to understand whether bus lines actually do anything. The wires that go to and from a bus have to have net labels, to show which links to which. The manual says that the bus entry lines are only cosmetic. But if they’re omitted KiCad has no way to know which bus line a wire is associated with. Finally, leaving both entries and bus lines out still works because wires with the same net label are considered connected together.
Have I missed something?
