Design Summary
--------------
Design Summary:
Number of errors: 0
Number of warnings: 0
Logic Utilization:
Number of Slice Flip Flops: 237 out of 3,840 6%
Number of 4 input LUTs: 852 out of 3,840 22%
Logic Distribution:
Number of occupied Slices: 504 out of 1,920 26%
Number of Slices containing only related logic: 504 out of 504 100%
Number of Slices containing unrelated logic: 0 out of 504 0%
*See NOTES below for an explanation of the effects of unrelated logic.
Total Number of 4 input LUTs: 936 out of 3,840 24%
Number used as logic: 852
Number used as a route-thru: 84
The Slice Logic Distribution report is not meaningful if the design is
over-mapped for a non-slice resource or if Placement fails.
Number of bonded IOBs: 29 out of 173 16%
Number of RAMB16s: 6 out of 12 50%
Number of BUFGMUXs: 2 out of 8 25%
Average Fanout of Non-Clock Nets: 2.90
Peak Memory Usage: 140 MB
Total REAL time to MAP completion: 4 secs
Total CPU time to MAP completion: 3 secs
NOTES:
Related logic is defined as being logic that shares connectivity - e.g. two
LUTs are "related" if they share common inputs. When assembling slices,
Map gives priority to combine logic that is related. Doing so results in
the best timing performance.
Unrelated logic shares no connectivity. Map will only begin packing
unrelated logic into a slice once 99% of the slices are occupied through
related logic packing.
Note that once logic distribution reaches the 99% level through related
logic packing, this does not mean the device is completely utilized.
Unrelated logic packing will then begin, continuing until all usable LUTs
and FFs are occupied. Depending on your timing budget, increased levels of
unrelated logic packing may adversely affect the overall timing performance
of your design.
