Using 'SIMULINK Support Package for Arduino Hardware' like 'LabVIEW'

Hello,

I am working on implementing LabVIEW-like functionality using the <SIMULINK Support Package for Arduino Hardware> and uploading it to an Arduino.

My goal is to implement hard constraints in Simulink (as I understand that Simulink's default behavior is soft constraint).

Here's my understanding of the concepts:

Hard constraint: In a 1kHz loop, if a loop started at time 't ms' exceeds 1ms, it stops processing the current sensor value (t ms) and moves to the next sensor value at 't+1 ms'.

Soft constraint: If the loop exceeds 1ms, it completes processing the current loop(t ms) and skips the next cycle(t+1 ms), moving to the loop with value at 't+2 ms'.

In LabVIEW, I understand that the `Deadline` command allows for implementing hard constraints.(Link: https://www.ni.com/docs/en-US/bundle/labview-api-ref/page/structures/timed-loop.html)

I tried to achieve this using `tic` and `toc` in the following code, but it failed to upload on the Arduino board

%% matlab code %%

function [num, y] = fcn(a,b)

persistent t

if isempty(t)

t = 0;

end

t = t+1;

num = t;

startTime = tic;

A = rand(a,b);

y = toc(startTime);

end

%%

Does anyone know a solution to this problem?

Thank you in advance.
