Hi, 

 

Altera also has IO buffers , these are called ALT_INBUF. Example :  

module io_primitives (data_in, data_out); input data_in; wire internal_sig; output data_out; alt_inbuf my_inbuf (.i(data_in), .o(internal_sig)); defparam my_inbuf.io_standard="1.8 V HSTL Class I"; assign data_out = !internal_sig; endmodule
