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 ...

1) when you turn off the auto DSP block replacement, means it will switch to ALM

2) How many FFT IP that you have use in your design? Is that fine for your to have certain IP to use ALM totally?

3) unless the FFT IP have a setting for you to control the usage, but seems there dont have.
