FFT sink_ready goes to x after reset deasserted

I have generated a 512 point fft and am attempting to run the simulation for the block,

When reset goes high, the sink_ready signal goes to an unkown instead of a 1 as expected.

Is there a minimum number of reset cycles that must occur in order to make this work properly?

I have added screen shots here to show the simulation output.

    Thanks for your inquiry. To facilitate the tracking, would you mind to open a new thread and share with me your design together with detailed steps to replicate the simulation observation. Please also help to share with me the Quartus version and device that you are using. Thank you.
