Bridges are used to control the topology of a Qsys system. The Avalon-MM Clock Crossing Bridge transfers Avalon-MM commands and responses between different clock domains. You can also use the Avalon-MM Clock Crossing Bridge to bridge between AXI masters and slaves of different clock domains. You can refer to the link below for more information.
