facing out of range error on Simulink.harness.create for SeparateAssessment value given as a true

Description: While creating test harness i am facing this error on "create.m" default script at this line

>> Simulink.harness.create(harnessOwner, varargin{:}); and when i am trying to go inside this it is telling it is .p script so unable to debug it. so, after run the script it is giving me this error "At least one value is out of range for rectangle or position. All x values must be within -32786..32767 range, all y values must be within -32786..32767 range

>> due to confidentiality i am unable to give u all the details but i came with more info regarding errror. i am running this command line "sltest.harness.create(ti_name,'Name', th_name, 'Source', 'Test Sequence', 'SeparateAssessment', true, 'SaveExternally', true, 'ScheduleInitTermReset', false, 'SchedulerBlock','None', 'HarnessPath', th_pfad);" so, as u can see here i am using "sltest.harness.create" function where 'SeparateAssessment' value is true. so, if i false that value so, i am able to generate the harness but it is without Assessment block but actually i need Assessment block also and if i give 'Separate'Assessment' true then it will error " "At least one value is out of range for rectangle or position. All x values must be within -32786..32767 range, all y values must be within -32786..32767 range" so, now how to resolve this issue while giving 'SeparateAssessment' as a true

Hi Vivek,

It sounds like you're encountering an issue related to the positioning of blocks within the test harness when using the `sltest.harness.create` function with the `SeparateAssessment` option set to `true`. The error message indicates that the position values of some blocks are out of the acceptable range.

Here are some steps to troubleshoot and potentially resolve the issue:

1. Check Initial Block Positions

Ensure that the initial positions of blocks in your model are within the acceptable range. If any block has a position outside the range of `[-32786, 32767]`, it could cause this error. Verify the positions of blocks in your model using the following command:

blocks = find_system('your_model_name', 'Type', 'Block');
positions = get_param(blocks, 'Position');

Inspect the `positions` array to ensure all values are within the specified range.

2. Adjust Block Positions

If you find any block positions out of range, adjust them to be within the acceptable limits. You can use the `set_param` function to update block positions:

set_param('your_model_name/block_path', 'Position', [x1, y1, x2, y2]);

Ensure that the new positions are within the range `[-32786, 32767]`.

3. Create a Custom Script to Adjust Positions

You can create a custom script to automatically adjust block positions if they are out of range. Here is an example script:

blocks = find_system('your_model_name', 'Type', 'Block');
for i = 1:length(blocks)
    pos = get_param(blocks{i}, 'Position');
    if any(pos < -32786) || any(pos > 32767)
        % Adjust positions to be within range
        pos(pos < -32786) = -32786;
        pos(pos > 32767) = 32767;
        set_param(blocks{i}, 'Position', pos);
    end
end

4. Use a Try-Catch Block

You can use a `try-catch` block to handle errors and provide more information about the block causing the issue:

try
    sltest.harness.create(ti_name, 'Name', th_name, 'Source', 'Test Sequence', ...
        'SeparateAssessment', true, 'SaveExternally', true, ...
        'ScheduleInitTermReset', false, 'SchedulerBlock', 'None', ...
        'HarnessPath', th_pfad);
catch ME
    disp('Error creating test harness:');
    disp(ME.message);
    % Additional debugging or logging can be done here
end

5. Update MATLAB

Ensure you are using the latest version of MATLAB and Simulink Test, as updates may contain bug fixes and improvements that could resolve this issue.

Example Script to Create Test Harness

Here is an example script that incorporates some of the suggestions above:

try
    % Adjust block positions if necessary
    blocks = find_system(ti_name, 'Type', 'Block');
    for i = 1:length(blocks)
        pos = get_param(blocks{i}, 'Position');
        if any(pos < -32786) || any(pos > 32767)
            pos(pos < -32786) = -32786;
            pos(pos > 32767) = 32767;
            set_param(blocks{i}, 'Position', pos);
        end
    end
    
    % Create test harness
    sltest.harness.create(ti_name, 'Name', th_name, 'Source', 'Test Sequence', ...
        'SeparateAssessment', true, 'SaveExternally', true, ...
        'ScheduleInitTermReset', false, 'SchedulerBlock', 'None', ...
        'HarnessPath', th_pfad);
catch ME
    disp('Error creating test harness:');
    disp(ME.message);
end

By following these steps, you should be able to identify and resolve the issue with block positions, allowing you to create the test harness with the `SeparateAssessment` option set to `true`.

I hope the above information helps you in resolving the issue.

Thank you.
