Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off clock -c clock
Info: Selected device EP2C8T144C8 for design "clock"
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: The Fitter has identified 1 logical partitions of which 0 have a previous placement to use
    Info: Previous placement does not exist for 162 of 162 atoms in partition Top
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
