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...

Yes that's what I'm going to do.

But do you know why ModelSim simulation failed to give correct CIC output? It's the same design... nothing changed.
