* Net Skew is the difference between the minimum and maximum routing
only delays for the net. Note this is different from Clock Skew which
is reported in TRCE timing report. Clock Skew is the difference between
the minimum and maximum path delays which includes logic delays.

WARNING:Par:62 - 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 "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/ise/implementation/Xplorer.htm 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.

Asterisk (*) preceding a constraint indicates it was not met.
   This may be due to a setup or hold violation.
