A Port () is a port model instance that you add to define the connections that devices uses to communicate with each other. To add this subnode, right-click a Device Model or Device Model Feature node and choose Port from the Devices submenu.

In the Name text field you enter the name of the port. This name defines the variable names that you use to access the variables declared in the port model that you refer to in the Type text field. If a port model declares a variable named v, and you typed a in the Name text field, you access the variable v by typing a.v.
