Maximum FFT Size supported in Variable streaming FFT

Hi,

We are using FFT IP Core 19.1 Quartus and using Variable Streaming with 2K FFT Points.

Does this ip core supports 2k when it is configured to Variable streaming. if not supported why it is working in simulation and IP configuration window also taking the value.

we are observing inconsistency in outputs source valid and data on board.

when we checked datasheet FFT IP CORE (17.1) it is given as 1k is max length supported when it is configured in Variable streaming.
