Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off cnt24 -c cnt24
Info: Selected device EP2C8T144C8 for design "cnt24"
Info: Fitter is performing an Auto Fit compilation, which may decrease Fitter effort to reduce compilation time
Info: Fitter is using the Classic Timing Analyzer
Info: Timing requirements not specified -- quality metrics such as performance and power consumption may be sacrificed 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 EP2C5T144C8 is compatible
    Info: Device EP2C5T144I8 is compatible
    Info: Device EP2C8T144I8 is compatible
Info: Fitter converted 3 user pins into dedicated programming pins
    Info: Pin ~ASDO~ is reserved at location 1
