Info: Command: quartus_fit --read_settings_files=off --write_settings_files=off ps2tolcd -c ps2tolcd
Info: Selected device EPM1270T144C5 for design "ps2tolcd"
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 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: Destination "div_256:inst1|clk" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[6]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[5]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[4]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[3]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[2]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[1]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|rx_ascii[0]" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|left_shift_key" may be non-global or may not use global clock
Info: Destination "ps2_keyboard_interface:inst3|right_shift_key" may be non-global or may not use global clock
Info: Limited to 10 non-global destinations
Info: Pin "reset" 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: Fitter placement preparation operations ending: elapsed time is 00:00:01
Info: Fitter placement operations beginning
Info: Fitter placement was successful
