3.3.2.4. Avalon Configuration Bus Interface Signals

The PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP exposes the Avalon memory-mapped-MM slave and Avalon memory-mapped master interfaces when you perform dynamic reconfiguration. Connect the Avalon memory-mapped slave to either a master in the core or the master interface of either an PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP or the External Memory Interface IP to be placed in the same column. You can only connect the master interface to the slave interface of a PHY Lite for Parallel Interfaces Intel® Stratix® 10 FPGA IP or External Memory Interface IP to be placed in the same column.
