VHO bug for FFT v2.2.1 (streaming)

I have simulated a 2048 point FFT v2.2.1 (streaming) in both ModelSim and Quartus. In Quartus correct streaming behaviour is observed, with assertion of master_source_sop immediately following asser...

Hello Wilhelm.

gate level simulation should be used, if the synthesis result is in doubt or device timing is the object of tests. But the Altera supplied functional simulation model should produce corect results as well. As reported, I experienced no irregularities with FFT v.2.2.0 model. Don't know if the difference is related to V2.2.1 model, the testbench or ModelSim version. Anyway, the real design behaviour counts.

Best regards,
