As per my understanding, you want to know how to create buffers in Simulink.
There are several different ways to create buffers in Simulink. You can refer to the below links to know more about them, and you can use one which best fits your use case:
- By using the "Buffer" block in Simulink: https://www.mathworks.com/help/dsp/ref/buffer.html
- You can also watch the following video for more information on Buffer Modelling: https://www.mathworks.com/videos/asynchronous-fifo-design-and-buffer-modeling-68922.html
- A utility created by one of our community members to model Buffer and UnBuffer blocks, using just Simulink Blocks: https://www.mathworks.com/matlabcentral/fileexchange/34128-buffer-and-unbuffer-using-simulink-blocks?s_tid=answers_rc2-2_p5_MLT
