Defining QoS Properties on NoC Connections - Defining QoS Properties on NoC Connections - 2026.1 English - UG1387

The XDC file creates the NoC connections. You need to define the QoS properties on these NoC connections. These properties include Bandwidth, Burst, and Latency. The command below shows an example for changing the properties on a NoC connection.

set_property -dict [list READ_BANDWIDTH 400 READ_AVERAGE_BURST 4 WRITE_BANDWIDTH 400 WRITE_AVERAGE_BURST 4] $conn0

Store the QoS properties in the same XDC constraint file as the NoC connections.

For more information on the QoS properties, refer to the following documents:
