I don't know how to display this image. I just attach the image address,you can click this address to see the image.

Actually, I can't capture the data by signaltapII which is output from ALT_DQDQS Megafunction, even this data is registered through many registers. Quartus come up a Internal error when assembler process when I capture the data from ALT_DQDQS or I output the data to output port,contrary,quartus assemler run successfully.

Thank you.
