Excellent intro to using Simulink/HDL Coder for signal processing!
Thanks for posting!!

Hi, is there any way to easily adapt this tutorial to R2018b? I am trying to run the testbench at step 7 and get the error:
Warning: Unconnected output line found on 'pulse_detector_v1/Discrete FIR Filter' (output port: 1)
> In pulse_detector_v1_tb (line 8)
Dot indexing is not supported for variables of this type.
Error in pulse_detector_v1_tb (line 11)
FilterOutSL = squeeze(slout.logsout.getElement('filter_out').Values.Data);

Hi Suranga - thanks for pointing that out. In 2019a Simulink changed the way it names the simulation workspace data. We have updated the kit for 2019a.

The example doesn't work with 2019a. I get the error "Undefined variable "logsout" or class "logsout.getElement"" when trying to run the model.

Figured out the answer to my own question - posting in case some one else makes the same mistake. I used the first simulink "from workspace" I saw. That block , from a comment in this link https://uk.mathworks.com/matlabcentral/answers/359452-error-input-uint8-simulink "From Workspace blocks are not able to import "just plain data". From Workspace blocks are intended to deliver data at a particular time: they are blocks for execution of a model, where as importing plain data is something that would be used in a procedural language.”".
As it turns out there are two simulink from workspace block. One specifies “signal from workspace” and can be used to import “just plain data”.
Summarily, make sure to use "signal from workspace". You'll get an error otherwise.
