FFT 7.1 streaming mode

Thanks for the reply anakha. I discovered the second problem was due to that I didn't follow some 'fine print' in the user guide (2-19 Compile the Design):

ensure the fft_pack_fft_71.vhd file is at the top of the list in the

file name list window.

Once I followed the instruction, the frame misalignment problem and some other strange issues were gone! I'm still puzzled why Quartus doesn't produce an error or warning message to stop this from happening.

My first problem still stands and I'm still waiting for a reply from Altera.
