Creating an N-Port Model

An N-port is a component whose behavior is specified by a set of frequency-dependent data such as S-parameters. To create an N-port element to place, select the Circuit project that contains it.

1. View the Component Libraries area, select the Symbols tab. Click Import Models.
2. Select the NPort icon. The Import Components window opens.

   

3. Browse to the directory containing the N-port data file, and select the file.
4. In Comp Name in the lower-right, change the component name if chosen.
5. Select a type for the Reference node:
• Implied reference to ground: the global ground is the reference port for each N port connection. Its voltage is always 0V.
• Common reference port: an additional reference pin is added that is a common reference for the definition of port voltages. This reference can have any voltage and corresponds to the net for that extra pin.
• Add individual hidden reference pin per port: an additional reference pin is added for each port. These reference pins are hidden, set to 0V by default, and can each have their own reference voltage. You can connect each reference pin to its own net. Select this option if you do not want to see the reference pins.
• Add individual reference pin per port: an additional reference pin is added for each port. Every reference pin can have its own reference voltage and be connected to its own net.

6. Click Open . An instance of the N-port component is attached to the cursor, so drag and place it in the schematic. When instances of the component are placed, right-click and select Finish or press Esc on the keyboard to stop placing instances.
