the best timing performance.   Unrelated logic shares no connectivity.  Map will only begin packing   unrelated logic into a slice once 99% of the slices are occupied through   related logic packing.   Note that once logic distribution reaches the 99% level through related   logic packing, this does not mean the device is completely utilized.   Unrelated logic packing will then begin, continuing until all usable LUTs   and FFs are occupied.  Depending on your timing budget, increased levels of   unrelated logic packing may adversely affect the overall timing performance   of your design.Mapping completed.See MAP report file "dianti_map.mrp" for details.
