FIR and CIC MegaCores Altogether

Hi, I have instantiated FIR II MegaCore as a Pulse-Shaping and upsampling by 8 filter, now I want to use CIC MegaCore after FIR to interpolate the signal... I didn't use Back Pressure feature in...

I do have it... but I can't simulate it... however, I used SignalTap to observe the output... it was distorted.

I connected "in_ready" output signal of CIC to the input "ast_source_ready" of FIR. I don't think there is much to do. Or is there?
