    INFO: Design contains EBR with ASYNC Reset Mode that has a limitation:
    The use of the EBR block asynchronous reset requires that certain timing
    be met between the clock and the reset within the memory block.
    See the device specific data sheet for additional details.




    INFO: Design contains pre-loadable EBR during configuration that has a
         requirement:
    Since the GSR is disabled for the EBR, make sure write enable and chip
    enable are inactive during wake-up, so that the pre-loaded initialization
    values will not be corrupted during wake-up state.
