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.
Try the Design Goal and Strategies for Timing Performance (In ISE select Project -> Design Goals & Strategies) to
ensure the best options are set in the tools for timing closure.
Use the Xilinx "SmartXplorer" script to try special combinations of
options known to produce very good results.
INFO:Timing:2761 - N/A entries in the Constraints list may indicate that the constraint does not cover any paths or that it has no
requested value.
Number of Timing Constraints that were not applied: 2
Asterisk (*) preceding a constraint indicates it was not met.
This may be due to a setup or hold violation.
