Total Number of 4 input LUTs: 33 out of 9,312 1% Number of bonded IOBs: 35 out of 232 15% Average Fanout of Non-Clock Nets: 2.20 Peak Memory Usage: 576 MB Total REAL time to MAP completion: 4 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.

Clock net lfsr_0/clk_i is sourced by a combinatorial pin. This is not good design practice. Use the CE pin to control the loading of data into the flip-flop. Section 3 - Informational ------------------------- INFO:MapLib:562 - No environment variables are currently set. INFO:LIT:244 - All of the single ended outputs in this design are using slew rate limited output drivers. The delay on speed critical single ended outputs can be dramatically reduced by designating them as fast outputs.
