Info: Running Quartus II Fitter
    Info: Version 6.0 Build 178 04/27/2006 SJ Full Version
    Info: Processing started: Wed Jun 25 09:18:46 2008
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off key0 -c key0
Info: Selected device EPM240T100C5 for design "key0"
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 EPM240T100I5 is compatible
    Info: Device EPM570T100C5 is compatible
    Info: Device EPM570T100I5 is compatible
Info: No exact pin location assignment(s) for 6 pins of 26 total pins
    Info: Pin row[3] not assigned to an exact location on the device
    Info: Pin en[4] not assigned to an exact location on the device
    Info: Pin en[5] not assigned to an exact location on the device
    Info: Pin en[6] not assigned to an exact location on the device
    Info: Pin en[7] not assigned to an exact location on the device
    Info: Pin column[3] not assigned to an exact location on the device
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: Automatically promoted signal "clk" to use Global clock in PIN 12
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: 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: 6 (unused VREF, 3.30 VCCIO, 1 input, 5 output, 0 bidirectional)
        Info: I/O standards used: 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 3.30V VCCIO pins. 8 total pin(s) used --  30 pins available
        Info: I/O bank number 2 does not use VREF pins and has 3.30V VCCIO pins. 12 total pin(s) used --  30 pins available
