3.10.1. 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 slave directly.

Intel recommends as an alternative that you instantiate the APB bridge and all the APB slaves in Platform Designer. You should then connect the slave side of the bridge to any high speed interface and connect the master side of the bridge to the APB slaves. 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 Avalon® /AXI bridge to export the Avalon® /AXI master to the top-level, and then connect this Avalon® /AXI interface to the slave side of the APB bridge. Alternatively, instantiate the APB bridge in Platform Designer and export APB master to the top- level, and from there connect to APB bus outside of Platform Designer.
