An NMU in AXI4-Stream mode may be configured to use one of two strategies to set the destination ID:

Fixed DestID
A configuration register in the NMU may be programmed 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 may optionally drive a logical destination ID onto the TDEST pins of the NMU. This logical destination ID is then mapped to a NoC compiler assigned DestID when Validate Design is run, and it is used to route the stream through the NoC. This enables M to N connection topologies.
