The controller can decouple/disable the bridges which prevents signal changes from passing through the bridge. The controller can also couple / enable the bridges which allows traffic to pass through the bridge normally. Xilinx LogiCORE Dynamic Function eXchange(DFX) AXI shutdown manager Softcore is compatible with the Xilinx LogiCORE pr-decoupler. The Dynamic Function eXchange AXI shutdown manager prevents AXI traffic from passing through the bridge. The controller safely handles AXI4MM and AXI4-Lite interfaces on a Reconfigurable Partition when it is undergoing dynamic reconfiguration, preventing the system deadlock that can occur if AXI transactions are interrupted by DFX.
