The name of the generated IP is set in the Component Name field. The default name is gtwizard_ultrascale_0 . This must be set to a name that is unique within your project.
The IP symbol is shown on the left-hand side of the Customize IP dialog box, and displays only enabled ports by default. It organizes input ports on the left-hand side of the symbol and output ports on the right-hand side. The IP symbol is updated as you make customization choices and use the optional ports enablement interface. See Product Specification for a detailed description of ports and their use.
