Info: Selected device EPM1270T144C5ES for design "da"
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 EPM1270T144C5 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 in PIN 18
Info: Automatically promoted some destinations of signal "clk1" to use Global clock
    Info: Destination "clk1" may be non-global or may not use global clock
    Info: Destination "clk_out~10" may be non-global or may not use global clock
Info: Automatically promoted some destinations of signal "clk2" to use Global clock
    Info: Destination "clk2" may be non-global or may not use global clock
    Info: Destination "clk_out~10" may be non-global or may not use global clock
Info: Automatically promoted some destinations of signal "clk0" to use Global clock
    Info: Destination "clk0" may be non-global or may not 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
