Info: Running Quartus II Fitter
    Info: Version 6.1 Build 201 11/27/2006 SJ Full Version
    Info: Processing started: Fri Oct 26 16:11:02 2007
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off barrel_shifter -c barrel_shifter
Info: Selected device EP2C5F256C6 for design "barrel_shifter"
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 35 of 35 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 EP2C8F256C6 is compatible
Info: Fitter converted 3 user pins into dedicated programming pins
    Info: Pin ~ASDO~ is reserved at location C3
    Info: Pin ~nCSO~ is reserved at location F4
    Info: Pin ~LVDS41p/nCEO~ is reserved at location N14
