I have been working in a windowing function that takes the input signal as a vector. When converting it with HDL Coder to VHDL, I find that this conversion is done as a parallel input, which is undesirable for my use case.
In some older documentation, I found the StreamingFactor setting which I've understood as the solution to my problem: It would convert the vector input to a sample-by-sample input.
The problem is that I've been unable to set this StreamingFactor within the HDL Coder Workflow, and in Simulink I can only import Verilog code which is also undesirable for my use case.
Is there any pragma or setting that would allow for the automatic conversion of vector inputs in MATLAB functions to streamed sample-by-sample VHDL code?

In this case, you want to use the Unbuffer block to stream the data in sample by sample.

Can you share a sample model that explains your usecase?
