Info: *******************************************************************
Info: Running Quartus II Fitter
    Info: Version 7.1 Build 156 04/30/2007 SJ Full Version
    Info: Processing started: Mon Dec 03 16:30:14 2007
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off ym4_1 -c ym4_1
Info: Selected device EP1C3T144C8 for design "ym4_1"
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 27 of 27 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 EP1C6T144C8 is compatible
Info: Fitter converted 2 user pins into dedicated programming pins
    Info: Pin ~nCSO~ is reserved at location 12
    Info: Pin ~ASDO~ is reserved at location 25
Warning: No exact pin location assignment(s) for 12 pins of 12 total pins
    Info: Pin ledout[0] not assigned to an exact location on the device
    Info: Pin ledout[1] not assigned to an exact location on the device
    Info: Pin ledout[2] not assigned to an exact location on the device
    Info: Pin ledout[3] not assigned to an exact location on the device
    Info: Pin ledout[4] not assigned to an exact location on the device
    Info: Pin ledout[5] not assigned to an exact location on the device
    Info: Pin ledout[6] not assigned to an exact location on the device
    Info: Pin ledout[7] not assigned to an exact location on the device
    Info: Pin ledin[0] not assigned to an exact location on the device
    Info: Pin ledin[1] not assigned to an exact location on the device
    Info: Pin ledin[2] not assigned to an exact location on the device
    Info: Pin ledin[3] not assigned to an exact location on the device
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: Completed User Assigned Global Signals Promotion Operation
Info: DQS I/O pins require 0 global routing resources
Info: Automatically promoted signal "Mux7~14" to use Global clock
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: Statistics of I/O pins that need to be placed that use the same VCCIO and VREF, before I/O pin placement
    Info: Number of I/O pins in group: 12 (unused VREF, 3.30 VCCIO, 4 input, 8 output, 0 bidirectional)
        Info: I/O standards used: 3.3-V LVTTL.
Info: I/O bank details before I/O pin placement
    Info: Statistics of I/O banks
        Info: I/O bank number 1 does not use VREF pins and has unused VCCIO pins. 2 total pin(s) used --  20 pins available
        Info: I/O bank number 2 does not use VREF pins and has unused VCCIO pins. 0 total pin(s) used --  28 pins available
        Info: I/O bank number 3 does not use VREF pins and has unused VCCIO pins. 0 total pin(s) used --  26 pins available
        Info: I/O bank number 4 does not use VREF pins and has unused VCCIO pins. 0 total pin(s) used --  28 pins available
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: Average interconnect usage is 0% of the available device resources. Peak interconnect usage is 0%
    Info: The peak interconnect region extends from location X0_Y0 to location X13_Y14
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
Warning: Following 1 pins have nothing, GND, or VCC driving datain port -- changes to this connectivity may change fitting results
    Info: Pin ledout[7] has GND driving its datain port
Warning: The Reserve All U
