Design Summary -------------- Design Summary: Number of errors: 0 Number of warnings: 89 Logic Utilization: Number of Slice Flip Flops: 463 out of 26,624 1% Number of 4 input LUTs: 437 out of 26,624 1% Logic Distribution: Number of occupied Slices: 343 out of 13,312 2% Number of Slices containing only related logic: 343 out of 343 100% Number of Slices containing unrelated logic: 0 out of 343 0% *See NOTES below for an explanation of the effects of unrelated logic. Total Number of 4 input LUTs: 449 out of 26,624 1% Number used as logic: 437 Number used as a route-thru: 12 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: 7 out of 487 1% IOB Flip Flops: 2 Number of BUFGMUXs: 2 out of 8 25% Average Fanout of Non-Clock Nets: 3.01 Peak Memory Usage: 281 MB Total REAL time to MAP completion: 2 secs Total CPU time to MAP completion: 2 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. Mapping completed.
