Error in port widths or dimensions. Output port 1 of 'untitled/Add' is a one dimensional vector with 64 elements

hi all,

I am exactly following this tutorial:https://www.youtube.com/watch?v=RbMzyN9Qspo

but when i run this model, i got the follwoing error

Error in port widths or dimensions. Output port 1 of 'untitled/Add' is a one dimensional vector with 64 elements

My question is, what am I doing wrong?

Hi Awais Ahmad,

After creating the Simulink model, run the pulse_detector_v1_tb.mlx testbench file available from the link: https://www.mathworks.com/matlabcentral/fileexchange/69651-hdl-coder-self-guided-tutorial as shown in the video.

Running the testbench file before running the model will not result in the error
