LogiCORE RapidIO - How does the core decide between TargetID field and TargetInfo field in the Target Response Port?


Which information is embedded in the packet when generating a RESPONSE packet (FType = 13), TRESP_TID or TRESP_MSG_SEG, TRESP_MBOX and TRESP_LETTER?

See RapidIO Packet Format Block Diagram in the Logical I/O Transport Layer User Guide.

How does the core decide which port to insert into the message?


The target_info is used for message responses (ttype = 4'b0001) when Doorbell and Messaging has been enabled. In all other instances, target_TID is used.
