Info: Running Quartus II Fitter
Info: Version 5.0 Build 148 04/26/2005 SJ Full Version
Info: Processing started: Sat Feb 18 12:15:49 2006
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off i2c -c i2c
Info: Selected device EPM1270T144C5 for design "i2c"
Info: Fitter is performing a Standard Fit compilation using maximum Fitter effort to optimize design performance
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 EPM570T144C5 is compatible
Info: Device EPM570T144I5 is compatible
Info: Device EPM1270T144I5 is compatible
Info: Device EPM1270T144C5ES is compatible
Info: Timing requirements not specified -- optimizing circuit to achieve the following default global requirements
Info: Assuming a global fmax requirement of 1000 MHz
Info: Assuming a global tsu requirement of 2.0 ns
Info: Assuming a global tco requirement of 1.0 ns
Info: Assuming a global tpd requirement of 1.0 ns
Info: Performing register packing on registers with non-logic cell location assignments
Info: Completed register packing on registers with non-logic cell location assignments
Info: Completed User Assigned Global Signals Promotion Operation
Info: Automatically promoted signal "clk" to use Global clock
Info: Pin "clk" drives global clock, but is not placed in a dedicated clock pin position
Info: Automatically promoted signal "rst" to use Global clock
Info: Pin "rst" drives global clock, but is not placed in a dedicated clock pin position
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: Moving registers into LUTs to improve timing and density
Info: Started processing fast register assignments
Info: Finished processing fast register assignments
Info: Finished moving registers into LUTs
Info: Finished register packing
Info: Fitter placement preparation operations beginning

Info: 5: + IC(0.575 ns) + CELL(2.322 ns) = 9.551 ns; Loc. = PIN_113; Fanout = 0; PIN Node = 'seg_data[4]'
Info: Total cell delay = 5.064 ns ( 53.02 % )
Info: Total interconnect delay = 4.487 ns ( 46.98 % )
Info: Fitter placement operations ending: elapsed time is 00:00:02
Info: Fitter routing operations beginning
Info: Average interconnect usage is 5% of the available device resources. Peak interconnect usage is 9%.
Info: Fitter routing operations ending: elapsed time is 00:00:02
Info: The following groups of pins have the same output enable
Info: The following pins have the same output enable: link
Info: Type bidirectional pin sda uses the LVTTL I/O standard
