Hi,
I'm trying to test FFT mega core v8.1 with ModelSim and meeting some problems about the signals.When using The FFT_tb.v generated by FFT MegaCore,the results are correct.But when using the tb file written by me in which I do not assert the sink_valid right after assert the reset_n(sink_valid asserted serval cycles after sink_ready asserted),the results are not completely correct.But I think it is not necessary to assert sink_valid at the moment sink_ready asserted. Does anyone can tell me how to deal with these problems? Thank you!Link Copied

The problem has been resovled just a moment ago.The resolution is to deassert sink_sop before sink_valid is asserted.
