Hello,
I have a question to the FFT reaction on source_ready.
After source_eop I set source_ready to '0' for 3 clock cycles and then set it to '1' again.

1 clock after source ready gone to '0' the source valid of the fft shows something like a "glitch"(?) and sets
source valid to '0' two clocks after that. With the next clock edge, source_valid is high again.
The number of clock cycles where source_ready is low seems to have no influence on this behavior. It also happens with 50 cycles
source_ready low.
For simulating I have used the auto-generated testbench from the MegaWizard Plugin Managerand compiled the .vho to the work library of
Modelsim.
Is this behavior normal or is my simulation somehow wrong? What can I do to solve the problem?
thanks in advance and best regards,
Andreas
