    Info: Processing started: Sun Mar 29 17:55:02 2009
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off 4encoder -c 4encoder
Info: Automatically selected device EP1S10F484C5 for design 4encoder
Info: Fitter is performing an Auto Fit compilation, which may decrease Fitter effort 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 248 of 248 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
    Info: Device EP1S20F484C5 is compatible
Info: Fitter converted 1 user pins into dedicated programming pins
    Info: Pin ~DATA0~ is reserved at location L8
