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

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?

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
