UltraRam Use option for FFT IP

I am using ZU15EG device. The FFT IP with 65536 points is a critical function for our application. I use multiple of these IPs in my design. In order to get uniform BRAM and UltraRAM usage, I would like to have GUI configuration selection for the UltraRAM memory for the FFT IP. 

Thanks

Re: UltraRam Use option for FFT IP

I am using a ZU19EG device and I would also like the capability to use UltraRAM for FFTs. Is this going to be an added capability going forward?

Re: UltraRam Use option for FFT IP

No. Very few of the DSP cores would benefit from these large memories mostly because they cannot be initialized as large ROM lookup-tables. For those few which would benefit, ultrarams will only be written in to the code opportunistically during a revisit prompted for other reasons in long term

Thanks and Regards
