You can modify the behavior for ports on your custom IP by defining restrictions on its use, as follows:

  1. Click a port in the Ports and Interfaces page, right-click and select Edit Port.
  2. In the Edit Port dialog box, shown in Editing a Port, set the following options:
    Driver Value
    If the port is disabled during customization, this is the driver value to the port.
    Port Presence
    Determines if the port can be disabled.
    Mandatory
    The option defines that the port are always available for the custom IP.
    Optional
    The option defines that the port is disabled when the expression in the text box is false. For more information on setting an enablement expression, see Setting a Dependency Expression.
    Important: Changing a port property does not affect the packaged HDL. Ensure the edited property matches the top-level HDL.
