6.11.1. Bridges

With APB, you cannot use bridge components that use multiple PSELx in Platform Designer. As a workaround, you can group PSELx, and then send the packet to the subordinate directly.

Intel recommends as an alternative that you instantiate the APB bridge and all the APB subordinates in Platform Designer. You should then connect the subordinate side of the bridge to any high speed interface and connect the manager side of the bridge to the APB subordinates. Platform Designer creates the interconnect on either side of the APB bridge and creates only one PSEL signal.

Alternatively, you can connect a bridge to the APB bus outside of Platform Designer. Use an AXI bridge to export the AXI manager to the top-level, and then connect this AXI interface to the subordinate side of the APB bridge. Alternatively, instantiate the APB bridge in Platform Designer and export APB manager to the top- level, and from there connect to APB bus outside of Platform Designer.
