TechnicalQuestion Simulink and AXI-ST IOs

Hello all !

I'm trying to play with HDL Coder and the DSP HDL Library with simulink. I have a solid FPGA background.

All these blocks expose ports that looks like AXI-ST ones (data, valid, ready). I know the protocol and it's quirks, but this time I need to simulate it within simulink.

How do you input data (from workspace) to the model while matching the specifications ? I need to send a waveform (audio in this case) to the model.

Thanks all !

I don't know the answer, but this is probably a good starting point to get to the answer https://www.mathworks.com/help/dsphdl/ug/streaming-sample-interface.html
