Help text

Say Y to enable drivers for Xilinx LogiCORE PR Decoupler or Xilinx Dynamic Function eXchange AIX Shutdown Manager. The PR Decoupler exists in the FPGA fabric to isolate one region of the FPGA from the busses while that region is being reprogrammed during partial reconfig. 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.
