Power Port

A power port is an electrical design primitive. It is a special schematic object that is used to define a power or ground net. Power ports allow you to conveniently indicate a power net at any location in the design, which can then be connected to pins or wires. Power nets of the same name automatically connect throughout the design, except in the following two situations.

  • If a Power Port is specifically wired to a Port object, that power net becomes local to that sheet. Net connections beyond the sheet must then be defined by the wiring of the Port/Sheet Entry combination.
  • When the Net Identifier Scope on the Options tab of the Project Options dialog is set to Strict Hierarchical, all power nets are set to local within each sheet.
