When would HDL Coder support FFT with run time configurable transform point size ?

Hello. Now HDL Coder only support fixed transform point size FFT with fixed-point data type. When would it support 1)run time configurable transform point size FFT 2)floating-point FFT

Could you please give some use cases for support so that we can consider the request for future releases?

Thanks. Please refer to https://www.xilinx.com/support/documentation/ip_documentation/xfft/v9_0/pg109-xfft.pdf In some cases, we have multiple input data size which need different FFT transform point size.If we use Xilinx IP with run time configurable transform point size option, it only occupy resource according to the biggest size.However, if we use HDL Coder IP, it would generate independent modules for each transform size.In addition, in some cases e.g. image processing,floating-point FFT is needed for precision requirement.
