You can configure an NMU in AXI4-Stream mode to use one of the following two strategies to set the destination ID:
- Fixed DestID
- You can program a configuration register in the NMU to contain a single destination ID. When enabled, the programmed value specifies the destination for all stream packets originating from that NMU. This enables 1 to 1 and M to 1 connection topologies.
- Master defined DestID
- Logic in the PL region can optionally drive a logical destination ID onto the Destination Interface pins of the NMU. This logical destination ID maps to a NoC compiler assigned DestID when you run Validate Design. It routes the stream through the NoC. This enables M to N connection topologies.
