Logic in the PL region may optionally drive the destination ID onto a set
of pins on the NMU boundary. This ID is then used to route the transaction through the
NoC to the intended NSU. The
destination interface pins are shown in the following table.
Interface Pin | Description |
---|---|
NMU_RD_DEST_MODE | Enable NMU_RD_USR_DST |
NMU_RD_USR_DST[11:0] | 12-bit destination ID to use for read transactions |
NMU_WR_DEST_MODE | Enable NMU_WR_USR_DST |
NMU_WR_USR_DST[11:0] | 12-bit destination ID to use for write transactions |
When a destination interface is enabled by driving the RD_DEST_MODE or WR_DEST_MODE pin high, the value on the corresponding USR_DST pins will override any address decode.
Note: NoC Master Specified Destination ID routing is not supported in the
current release.
