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.

You can only find it in the IP catalog of platform designer. Go to Tools > Platform Designer.
