The final step to the Modular NoC flow is to validate the NoC. This is achieved by running the validate_noc Tcl command. Before running this command, all BDs and IPs that are present in the design must be generated. The validate_noc command initiates RTL elaboration, applies NoC constraints from XDC, and invokes the NoC compiler.

Additionally, the validate_noc command includes multiple embedded design rule checks (DRCs) to ensure the validity of the overall system-level NoC solution. After the validate_noc command is completed, the project-level NoC view is opened and the vivado.log reflects the NoC constraints being applied.

Figure 2. Project-Level NoC View

In the project-level NoC view, the NoC Objects window shows all the XPM NMUs/NSUs that you instantiated in the RTL.

You can open the project-level NoC view at any time. Click the Project Manager in the Flow Navigator. Select the Window menu and click the NoC option.

Figure 4. Opening Project-Level NoC View
Note: The project-level NoC view appears the same as a BD level NoC view. If you select IP Integrator in the Flow Navigator, the BD NoC view appears. Selecting Project Manager shows the project-level NoC view. The BD NoC view shows a subset of the project-level NoC view. XPM NoC instances are only visible in the project-level NoC view.

The project-level NoC view shows all NoC information in the design regardless of its origin. The BD level NoC view only shows the NoC information from the context of the BD.
