"prescale_counter" is an NCD, version 3.1, device xc5vlx30t, package ff665, speed -3Initializing temperature to 85.000 Celsius. (default - Range: 0.000 to 85.000 Celsius)Initializing voltage to 0.950 Volts. (default - Range: 0.950 to 1.050 Volts)INFO:Par:282 - No user timing constraints were detected or you have set the option to ignore timing constraints ("par
-x"). Place and Route will run in "Performance Evaluation Mode" to automatically improve the performance of all
internal clocks in this design. The PAR timing summary will list the performance achieved for each clock. Note: For
the fastest runtime, set the effort level to "std". For best performance, set the effort level to "high". For a
balance between the fastest runtime and best performance, set the effort level to "med".Device speed data version: "ADVANCED 1.49 2006-10-19".INFO:Par:253 - The Map -timing placement will be retained since it is likely to achieve better performance.Device Utilization Summary: Number of BUFGs 1 out of 32 3% Number of External IOBs 34 out of 360 9% Number of LOCed IOBs 0 out of 34 0% Number of Slice Registers 32 out of 19200 1% Number used as Flip Flops 32 Number used as Latches 0 Number used as LatchThrus 0 Number of Slice LUTS 33 out of 19200 1% Number of Slice LUT-Flip Flop pairs 34 out of 19200 1%Overall effort level (-ol): Standard Router effort level (-rl): Standard Starting RouterPhase 1: 134 unrouted; REAL time: 1 mins 35 secs Phase 2: 94 unrouted; REAL time: 1 mins 35 secs Phase 3: 2 unrouted; REAL time: 1 mins 35 secs Phase 4: 2 unrouted; (0) REAL time: 1 mins 35 secs Phase 5: 2 unrouted; (0) REAL time: 1 mins 35 secs Phase 6: 0 unrouted; (0) REAL time: 1 mins 35 secs Phase 7: 0 unrouted; (0) REAL time: 1 mins 35 secs Phase 8: 0 unrouted; (0) REAL time: 1 mins 35 secs Phase 9: 0 unrouted; (0) REAL time: 1 mins 36 secs Total REAL time to Router completion: 1 mins 36 secs Total CPU time to Router completion: 1 mins 29 secs Partition Implementation Status------------------------------- No Partitions were found in this design.-------------------------------Generating "PAR" statistics.**************************Generating Clock Report**************************+---------------------+--------------+------+------+------------+-------------+| Clock Net | Resource |Locked|Fanout|Net Skew(ns)|Max Delay(ns)|+---------------------+--------------+------+------+------------+-------------+| clk_BUFGP | BUFGCTRL_X0Y0| No | 10 | 0.011 | 1.159 |+---------------------+--------------+------+------+------------+-------------+* Net Skew is the difference between the minimum and maximum routingonly delays for the net.
