I am learning Altium Designer and now I am working on some multisheet pcb project, which consists of Power Supply among other things, which is implemented with
Texas Instruments's UA7805 Regulator for +5V/1.5A power supply rail. This rail is named in schematic as +5V_DIGITAL. However, because of multisheet design (with root sheet), how do I declare this power rail in Altium, as Power port:
or as Port:
? If rail should/must be declared as Port, then what type of port it is (Unspecified, Output or Bidirectional)?
Electronic – Multisheet design power rail as port or as power port

Figured out a workaroud: Made the sheet containing the channel sheets the top sheet by adding sheet symbols for the two other subsystems in the design.

Ports are mainly for signals, not rails. I always use option #1, with a power port. The benefit to this is that (depending on your project settings) the power ports are global so you don't need any sort of sheet-to-sheet connector to connect the power ports between sheets. The connection is implicit.
