5.12.2. QoS

Platform Designer routes 4-bit QoS signals (Quality of Service Signaling) on the read and write address channels directly from the master or host to the slave or agent.

Transactions from AMBA* 3 AXI masters and Avalon® hosts have a default value of 4'b0000, which indicates that the transactions are not part of the QoS flow. QoS values are not used for slaves or agents that do not support QoS.

For Platform Designer 14.0, there are no programmable QoS registers or compile-time QoS options for a master or host that overrides its real or default value.
