Info: Running Quartus II Fitter
    Info: Version 6.0 Build 178 04/27/2006 SJ Full Version
    Info: Processing started: Sat Apr 12 10:42:26 2008
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off onebitadder -c onebitadder
Info: Selected device EP1C3T144C8 for design "onebitadder"
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 EP1C6T144C8 is compatible
Info: Timing requirements not specified -- quality metrics such as performance and power consumption may be sacrificed to reduce compilation time.
Info: Completed User Assigned Global Signals Promotion Operation
Info: DQS I/O pins require 0 global routing resources
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: Finished moving registers into I/O cells, LUTs, and RAM blocks
Info: Finished register packing: elapsed time is 00:00:00
Info: Fitter placement preparation operations beginning
Info: Fitter placement preparation operations ending: elapsed time is 00:00:00
Info: Fitter placement operations beginning
Info: Fitter placement was successful
Info: Fitter placement operations ending: elapsed time is 00:00:00
Info: Fitter routing operations beginning
Info: Fitter routing operations ending: elapsed time is 00:00:00
Info: The Fitter performed an Auto Fit compilation.  Optimizations were skipped to reduce compilation time.
    Info: Optimizations that may affect the design's routability were skipped
    Info: Optimizations that may affect the design's timing were skipped
Info: Completed Fixed Delay Chain Operation
Info: Started post-fitting delay annotation
Info: Delay annotation completed successfully
Info: Completed Auto Delay Chain Operation
Info: Quartus II Fitter was successful. 0 errors, 0 warnings
