The following are some suggestions to assist you to meet timing in your
   design.
      Review the timing report using Timing Analyzer (In ISE select "Post-Place &      Route Static Timing Report").  Go to the failing constraint(s) and select      the "Timing Improvement Wizard" link for suggestions to correct each problem.   Run Multi-Pass Place and Route in PAR using at least 5 "PAR Iterations"   (ISE process "Multi Pass Place & Route").   Use the Xilinx "xplorer" script to try special combinations of   options known to produce very good results.   See http://www.xilinx.com/xplorer for details.   Visit the Xilinx technical support web at http://support.xilinx.com and go to   either "Troubleshoot->Tech Tips->Timing & Constraints" or "   TechXclusives->Timing Closure" for tips and suggestions for meeting timing   in your design.Number of Timing Constraints that were not applied: 27Asterisk (*) preceding a constraint indicates it was not met.
