Hi,

I'm trying to compile with EP3C120 developement kit board... I have

some criticals warning

i have erros "can't fit" when i set value to 12mA

Any ideas? Thanks.

    You should mention the explaining text with error message "can't fit" and the Quartus version. Also, did you include all I/O settings (tcl-files) generated by the Megawizard?

    Yes include all tcl files...

    O.K., so you are using a 50 or 25 ohm termination setting for the pins. Only one IO-strength setting can be active at a time, termination isn't but a different form of current strength setting. The above warning should be regarded as a Quartus bug in this case and can be ignored. You may want to check in the fitter report, that the intended setting have been actually applied. And report the apparent bug to Altera support.
