Design Summary
--------------
Number of errors:      0
Number of warnings:   51
Logic Utilization:
  Number of Slice Flip Flops:           237 out of  15,360    1%
  Number of 4 input LUTs:               557 out of  15,360    3%
Logic Distribution:
  Number of occupied Slices:            347 out of   7,680    4%
    Number of Slices containing only related logic:     347 out of     347 100%
    Number of Slices containing unrelated logic:          0 out of     347   0%
      *See NOTES below for an explanation of the effects of unrelated logic.
  Total Number of 4 input LUTs:         597 out of  15,360    3%
    Number used as logic:               557
    Number used as a route-thru:         40

  The Slice Logic Distribution report is not meaningful if the design is
  over-mapped for a non-slice resource or if Placement fails.

Section 10 - Timing Report
--------------------------
A logic-level (pre-route) timing report can be generated by using Xilinx static
timing analysis tools, Timing Analyzer (GUI) or TRCE (command line), with the
mapped NCD and PCF files. Please note that this timing report will be generated
using estimated delay information. For accurate numbers, please generate a
timing report with the post Place and Route NCD file.

For more information about the Timing Analyzer, consult the Xilinx Timing
Analyzer Reference Manual; for more information about TRCE, consult the Xilinx
Command Line Tools User Guide "TRACE" chapter.
