Interface Ports

An interface port serves as a named connector, whether the port is currently within a design or not. The interface port parameters specify the port name, its impedance, a reference node, and one or more power/current/voltage source specifications.

To place an interface port, select the schematic that contains it, then do one of the following:

• From the Draw menu, select Interface Port.
• From the Schematic Draw toolbar, click the Interface Port icon .

The cursor, which is now associated with an interface port symbol for placement, moves to the center of the schematic window. To place the port, click at the appropriate location. (If Multiple Placement is activated for interface ports in the Schematic Options window, place additional ports by clicking at additional locations.)

To stop placing interface ports, do one of the following:

• Press Enter, the Spacebar, or Esc on your keyboard.
• Right-click, then select Place and Finish, Finish, or Cancel.
