Release 14.6 Map P.68d (nt64) Xilinx Mapping Report File for Design 'BCD_to_Excess3' Design Information ------------------ Command Line : map -intstyle ise -p xc3s500e-fg320-4 -cm area -ir off -pr off -c 100 -o BCD_to_Excess3_map.ncd BCD_to_Excess3.ngd BCD_to_Excess3.pcf Target Device : xc3s500e Target Package : fg320 Target Speed : -4 Mapper Version : spartan3e -- $Revision: 1.55 $ Mapped Date : Tue Aug 26 20:37:20 2014 Design Summary -------------- Number of errors: 0 Number of warnings: 0 Logic Utilization: Number of 4 input LUTs: 5 out of 9,312 1% Logic Distribution: Number of occupied Slices: 3 out of 4,656 1% Number of Slices containing only related logic: 3 out of 3 100% Number of Slices containing unrelated logic: 0 out of 3 0% *See NOTES below for an explanation of the effects of unrelated logic. Total Number of 4 input LUTs: 5 out of 9,312 1% Number of bonded IOBs: 9 out of 232 3% Average Fanout of Non-Clock Nets: 3.00 Peak Memory Usage: 274 MB Total REAL time to MAP completion: 2 secs Total CPU time to MAP completion: 1 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.

WARNING:Security:44 - Since no license file was found, WARNING:Security:42 - Your software subscription period has lapsed. Your current version of Xilinx tools will continue to function, but you no longer qualify for Xilinx software updates or new releases. Section 3 - Informational ------------------------- INFO:Security:51 - The XILINXD_LICENSE_FILE environment variable is not set. INFO:Security:52 - The LM_LICENSE_FILE environment variable is set to '1417@ephesus.ece.iit.edu;1717@valkyrie.ece.iit.edu;27000@skew.ece.iit.edu'. INFO:Security:54 - 'xc3s500e' is a WebPack part. 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.
