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...

There is also issue of using different clock rates on FIR and CIC. Do you need that. You better use same system clock or it may go wrong
