I'm having trouble with simulating FFT in ModelSim.
Althoug i've asserted all input signals (as shown on figure_1(2019.06.20 20-01-25)), output of FFT stuck at zero.
No valids, no SOP/EOP or data.
RST_n and source_ready are always high.
Has anyone encountered such problem or does anyone know a key to resolving it?
Thanks in advance for your replies)
(PS also ModelSim shows warning, represented on figure_2(2019.06.20 20-01-410))
You probably just need to assert reset at the beginning of your sim to get the core to a known state. From the looks of your screenshot, your reset is never low at the start...
