Info: Running Quartus II Fitter
    Info: Version 7.0 Build 33 02/05/2007 SJ Full Version
    Info: Processing started: Wed Apr 30 06:55:50 2008
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off a2d -c a2d
Info: Selected device EPM1270T144C5 for design "a2d"
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 EPM1270T144I5 is compatible
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: Automatically promoted signal "clk" to use Global clock in PIN 18
Info: Automatically promoted some destinations of signal "sw0" to use Global clock
    Info: Destination "t_sck" may be non-global or may not use global clock
    Info: Destination "t_dacs" may be non-global or may not use global clock
    Info: Destination "t_dasck~477" may be non-global or may not use global clock
    Info: Destination "ram_part_addr[3]" may be non-global or may not use global clock
    Info: Destination "t_int[0]~408" may be non-global or may not use global clock
    Info: Destination "count2[5]~1029" may be non-global or may not use global clock
    Info: Destination "count3[0]~2092" may be non-global or may not use global clock
    Info: Destination "comb~21" may be non-global or may not use global clock
    Info: Destination "ram_part_addr[2]~4857" may be non-global or may not use global clock
    Info: Destination "comb~3774" may be non-global or may not use global clock
    Info: Limited to 10 non-global destinations
Info: Pin "sw0" 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
