using DSPs in the FPGA as ALMs for standard FFT IP

Hi, We are using standard FPGA FFT IP for our design given by intel. we want to use many FFT IPs parallely for that the problem that we are seeing is resources for ALMs required is not suffiecient ...

    The whole point is that you are doing this project from start with 16.1 something you made in 18.1 downgrading or something like that to 16.1 so it is working. I applied your things in other project of 16.1 and nothing is working , I just saw the synthesis settings to match everything and all are same. still DSP are not getting consumed. In your project given by you also you can see the difference between the component you instantiated and actual block is different of the IP, you can the see in the following picture. If possible please try to create everything from scratch in 16.1 and show me this happen, otherwise no use.

    you can source_exp in block diagram but you mentioned fftps_out which is in 18.1 IP component.
