Info: Running Quartus II Fitter
    Info: Version 7.2 Build 207 03/18/2008 Service Pack 3 SJ Full Version
    Info: Processing started: Thu Jun 26 11:44:00 2008
Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off rcvr -c rcvr
Info: Selected device EPM1270T144C5 for design "rcvr"
Warning: The high junction temperature operating condition is not set. Assuming a default value of '85'.
Warning: The low junction temperature operating condition is not set. Assuming a default value of '0'.
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 EPM570T144C5 is compatible
    Info: Device EPM570T144I5 is compatible
    Info: Device EPM570T144A5 is compatible
    Info: Device EPM1270T144I5 is compatible
    Info: Device EPM1270T144A5 is compatible
Info: Fitter is using the Classic Timing Analyzer
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: Completed User Assigned Global Signals Promotion Operation
Info: Automatically promoted signal "clk" to use Global clock in PIN 18
Info: Automatically promoted some destinations of signal "rcvr:inst|clk1x" to use Global clock
    Info: Destination "rcvr:inst|clk1x" may be non-global or may not use global clock
Info: Automatically promoted some destinations of signal "txt:inst1|clk1x" to use Global clock
    Info: Destination "txt:inst1|clk1x" may be non-global or may not use global clock
Info: Automatically promoted some destinations of signal "wrn" to use Global clock
    Info: Destination "txt:inst1|wrn1" may be non-global or may not use global clock
Info: Pin "wrn" 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: Started processing fast register assignments
Info: Finished processing fast register assignments
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: Estimated most critical path is register to pin delay of 4.106 ns
    Info: 1: + IC(0.000 ns) + CELL(0.000 ns) = 0.000 ns; Loc. = LAB_X9_Y10; Fanout = 1; REG Node = 'rcvr:inst|rbr[7]'

    Info: Total cell delay = 2.322 ns ( 56.55 % )
    Info: Total interconnect delay = 1.784 ns ( 43.45 % )
Info: Fitter routing operations beginning
Info: Average interconnect usage is 1% of the available device resources
    Info: Peak interconnect usage is 2% of the available device resources in the region that extends from location X0_Y0 to location X8_Y11
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
Warning: The Reserve All Unused Pins setting has not been specified, and will default to 'As output driving ground'.
