    Info: Processing started: Thu Nov 22 16:56:21 2007
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off nand_interface -c nand_interface
Info: Selected device EPM240GT100C3 for design "nand_interface"
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 EPM570GT100C3 is compatible
Warning: No exact pin location assignment(s) for 13 pins of 13 total pins
    Info: Pin ce not assigned to an exact location on the device
    Info: Pin re not assigned to an exact location on the device
    Info: Pin ale not assigned to an exact location on the device
    Info: Pin cle not assigned to an exact location on the device
    Info: Pin se not assigned to an exact location on the device
    Info: Pin we not assigned to an exact location on the device

    Info: Pin e_d not assigned to an exact location on the device
    Info: Pin reset 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: 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: 13 (unused VREF, 3.30 VCCIO, 6 input, 7 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 --  38 pins available
        Info: I/O bank number 2 does not use VREF pins and has undetermined VCCIO pins. 0 total pin(s) used --  42 pins available
