Pin's logic level setting

[akita11]

With using the template project, there are no specification on pin's logic level in *.lpf file, and this results in logic level of LVCMOS25, CMOS 2.5V. Since vccio is connected to VDD(3.3V), logic level should be LVCMOS33, CMOS 3.3V. How to specify it?

Adding following line to *.lpf seems to set all IOs to be LVCMOS33.
IOBUF ALLPORTS IO_TYPE=LVCMOS33 ;
