Info: *******************************************************************
Info: Running Quartus II Fitter
Info: Version 5.0 Build 148 04/26/2005 SJ Full Version
Info: Processing started: Sat Feb 18 13:48:12 2006
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off clock -c clock
Info: Selected device EPM1270T144C5 for design "clock"
Info: Fitter is performing a Standard Fit compilation using maximum Fitter effort to optimize design performance
Info: Device migration not selected. If you intend to use device migration later, you may need to change the pin assignments as they may be incompatible with other devices.
Info: Device EPM570T144C5 is compatible
Info: Device EPM570T144I5 is compatible
Info: Device EPM1270T144I5 is compatible
Info: Device EPM1270T144C5ES is compatible
Info: Timing requirements not specified -- optimizing circuit to achieve the following default global requirements
Info: Assuming a global fmax requirement of 1000 MHz
Info: Assuming a global tsu requirement of 2.0 ns
Info: Assuming a global tco requirement of 1.0 ns
Info: Assuming a global tpd requirement of 1.0 ns
Info: Performing register packing on registers with non-logic cell location assignments
Info: Completed register packing on registers with non-logic cell location assignments
Info: Completed User Assigned Global Signals Promotion Operation
Info: Automatically promoted signal "clk" to use Global clock
Info: Pin "clk" drives global clock, but is not placed in a dedicated clock pin position
Info: Automatically promoted signal "rst" to use Global clock
Info: Pin "rst" drives global clock, but is not placed in a dedicated clock pin position
Info: Completed Auto Global Promotion Operation
Info: Starting register packing
Info: Fitter is using Normal packing mode for logic elements with Auto setting for Auto Packed Registers logic option
Info: Moving registers into LUTs to improve timing and density
Info: Started processing fast register assignments
Info: Finished processing fast register assignments
Info: Finished moving registers into LUTs
Info: Finished register packing
Info: Fitter placement preparation operations beginning
Info: Fitter placement preparation operations ending: elapsed time is 00:00:00
Info: Fitter placement operations beginning
Info: Fitter placement was successful
Info: Estimated most critical path is register to pin delay of 14.758 ns
