get_noc_interfaces - get_noc_interfaces - 2026.1 English - UG1387

The get_noc_interfaces command provides a list of all available NMU/NSU interfaces in the design. It includes interfaces from all design sources. These sources include DCPs, Block Designs, RTL files, and EDIF netlists. Before making NoC connections in the XDC file, you can take the reference of the get_noc_interfaces command by executing it in the Tcl Console. The following code snippet shows the output of the get_noc_interfaces when executed in the Tcl Console.

The get_noc_interfaces has the following command-line switches:

-mode

Filters the NoC interfaces by mode. Valid values are NMU and NSU. The following code snippet shows the -mode switch usage.

Figure 2. -mode Code Example

-type

Filters the NoC interfaces by type. Valid values are AXIMM and AXIS and the default value is AXIMM. The following code snippet shows the -type switch usage.

-category

Filters the NoC interface by category. Default is PL. The following code snippet shows the -category switch usage.

To report all the properties of the NoC interface, you can use the report_property –all command for the NoC interface in the Vivado Tcl Console. You can modify traffic classes by setting READ_TRAFFIC_CLASS and WRTIE_TRAFFIC_CLASS properties on NMU NoC instances. To set an ISOCHRONOUS traffic class on a given noc_interface, use the following set_property command:

set_property -dict [list READ_TRAFFIC_CLASS ISOCHRONOUS WRITE_TRAFFIC_CLASS ISOCHRONOUS] [lindex [get_noc_interfaces] 1]
