title: In xilinx vivado how to find the maximum frequency in the report similar to xilinx 14.7
body: <h2>Timing Summary:</h2>
  <p>Speed Grade: -1</p>
  <p>Minimum period: 4.979ns (Maximum Frequency: 200.844MHz)
  Minimum input arrival time before clock: 1.459ns
  Maximum output required time after clock: 0.833ns
  Maximum combinational path delay: No path found
  This is obtained from xilinx 14.7 same cannot be found in xilinx vivado and by adding constraint wizard and calculating 1/(T-WNS ) = MAX Frequency is too low when compared with same programs in two different tool (but same hardware and same program)</p>
