Logic in the PL region can optionally drive the destination ID onto a set of
pins on the NMU boundary. The logic then uses this ID to route the transaction through
the NoC to the intended NSU. The following
table shows the destination interface pins.
| 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 |
Drive RD_DEST_MODE or WR_DEST_MODE high to enable the destination interface. The value on the corresponding USR_DST pins then overrides any address decode.
Note: The current release does not
support NoC Master Specified Destination ID routing.
