In multi-SLR devices, the NoC enables programming and access across SLRs. You can access these paths using the PMC[3:0]_alias address ranges. Refer to the NoC Address Map in Versal Adaptive SoC Technical Reference Manual (AM011). The handling of these paths is mostly hidden, however, consider the following points:
- For Exclusive Routing Groups, the existence of the boot paths can conflict with user exclusive routing groups. In multi-SLR devices, the number of possible achievable exclusive routing groups can be reduced by the NoC compiler to accommodate the boot path route. In general, the leftmost VNoC in multi-SLR devices serves the boot path and is not available for exclusive routing groups.
- For bandwidth/QoS, a small amount of bandwidth is allocated to the boot paths. Thus, there is a slight reduction in the maximum achievable QoS solution on the paths shared with the hidden NoC boot paths. These routes are hidden, but they always use the same path through the NoC on a particular device.
