The Routing tab of the Customize IP dialog box is shown in the following figure.

Figure 1. Routing Tab

The Routing tab is used to define the decoding used by the NoC to route AXI4-Stream traffic from NMU to NSU based on the TDEST signal. Each NSU must have a BASE/HIGH range that is within the valid width of the TDEST width specified on the General tab. The BASE/HIGH pair must not overlap NSU interfaces. When a transfer is received at the NMU, the TDEST is decoded based on the table, and ultimately converted to the DestID of the intended NSU. This enables M:N routing of AXI4-Stream traffic. The decode_err output indicates that a incoming transfer has an TDEST value that does not map to a valid Master Interface. Invalid TDEST transfers are dropped. The output is only valid if the TDEST signal is present and used for routing.
