ALTDDIO_OUT. How to overcome restrictions on output data port?

[Altera_Forum]

Hello! 

 In the Double Data Rate I/O Megafunctions datasheet it is said, that DDR output data port of ALTDDIO_OUT ( dataout[] ) should directly feed output pins in top-level design. But in my design I need to feed these outputs to inputs of another block inside my design. That , of course, causes Quartus errors. Is there a workaround for this problem?

Inside fpga there is no ddr support as you can just double your clock.

And you can just build it in RTL. The altddio_out is meant to call the dedicated structure built in the I/O cell.
