The Map -timing placement will be retained since it is likely to achieve better performance. The signal An<2>_IBUF has no load. PAR will not attempt to route this signal. N/A entries in the Constraints list may indicate that the constraint does not cover any paths or that it has no requested value. There are 1 loadless signals in this design. This design will cause Bitgen to issue DRC warnings. There are 1 loadless signals in this design. This design will cause Bitgen to issue DRC warnings.
