    Info: Processing started: Thu Jul 31 10:55:42 2008
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off music_work -c music_work
Info: Selected device EPM1270T144C5ES for design "music_work"
Warning: The high junction temperature operating condition is not set. Assuming a default value of '85'.
Warning: The low junction temperature operating condition is not set. Assuming a default value of '0'.
Info: Fitter is performing an Auto Fit compilation, which may decrease Fitter effort to reduce compilation time
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 EPM1270T144C5 is compatible
    Info: Device EPM1270T144I5 is compatible
Warning: No exact pin location assignment(s) for 3 pins of 3 total pins
    Info: Pin clock_out not assigned to an exact location on the device
    Info: Pin clock not assigned to an exact location on the device
    Info: Pin en not assigned to an exact location on the device
Info: Fitter is using the Classic Timing Analyzer
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: Completed User Assigned Global Signals Promotion Operation
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: Started processing fast register assignments
Info: Finished processing fast register assignments
Info: Finished register packing: elapsed time is 00:00:00
Info: Statistics of I/O pins that need to be placed that use the same VCCIO and VREF, before I/O pin placement
    Info: Number of I/O pins in group: 3 (unused VREF, 3.30 VCCIO, 2 input, 1 output, 0 bidirectional)
        Info: I/O standards used: 3.3-V LVTTL.
Info: I/O bank details before I/O pin placement
    Info: Statistics of I/O banks
        Info: I/O bank number 1 does not use VREF pins and has undetermined VCCIO pins. 0 total pin(s) used --  26 pins available
        Info: I/O bank number 2 does not use VREF pins and has undetermined VCCIO pins. 0 total pin(s) used --  30 pins available
        Info: I/O bank number 3 does not use VREF pins and has undetermined VCCIO pins. 0 total pin(s) used --  30 pins available

    Info: Total cell delay = 4.194 ns ( 65.09 % )
    Info: Total interconnect delay = 2.249 ns ( 34.91 % )
Info: Fitter routing operations beginning
Info: Average interconnect usage is 0% of the available device resources
    Info: Peak interconnect usage is 0% of the available device resources in the region that extends from location X0_Y0 to location X8_Y11
Info: Fitter routing operations ending: elapsed time is 00:00:00
Info: The Fitter performed an Auto Fit compilation.  Optimizations were skipped to reduce compilation time.
    Info: Optimizations that may affect the design's routability were skipped
    Info: Optimizations that may affect the design's timing were skipped
Warning: The Reserve All Unused Pins setting has not been specified, and will default to 'As output driving ground'.
