The traffic specification defines the operation of the NoC. It is a description that specifies every connection though the NoC and its associated Quality of Service (QoS) requirement. This traffic specification runs through the NoC compiler to compute a NoC configuration which satisfies the requirements.
You can define the traffic specification in Vivado
IP integrator by double-clicking the NoC/NoC2 IP in IP
integrator. Use the Inputs and Outputs
tabs to specify the interfaces to the NoC infrastructure. Use the Connectivity and QoS tabs to define the traffic specification.
Refer to Configuring the AXI NoC.

Alternatively, use the Tcl command noc_create_traffic to define the
traffic specification.
