<msg type="info" file="Par" num="62" delta="unknown" >Your design did not meet timing.  The following are some suggestions to assist you to meet timing in your design.

   Review the timing report using Timing Analyzer (In ISE select &quot;Post-Place &amp;
   Route Static Timing Report&quot;).  Go to the failing constraint(s) and select
   the &quot;Timing Improvement Wizard&quot; link for suggestions to correct each problem.
