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 ...

Thanks for attaching the design.qar files. Looking into the FFT module, most of the .v is encrypted. DSP block usually was used when there are multiplication take place. Since those files are encrypted, you cannot force those design to use the dsp block.

Unless you create your own design, then you will have better control of it.

But You can see in your datasheet it will consume DSPs but according to the datasheet also not happening no. Then how the number in the datasheet for DSP consumption given.
