How do I add a DOORs requirement link to a block in the simulink using code.

I found to set the DOORs template but not to append a new DOORs requirement

The following commands allows me to set and update all the requirements traced to a model.

->rmi('setDoorsLabelTemplate', '%h %200'); and rmi('updateDoorsLabels', example_model);

I need commands to append a new DOORs requirement to the existing tracing in the model:

Similar to these commands:

new_req = rmi('createempty');

new_req.doc = 'fuelsys_requirements2.htm';

new_req.description = 'A new requirement';

rmi('cat', blk_with_req, new_req);

Hi @Pavan Rachapudi,

I see that you want to append a new requirement to an existing set of requirements traced to a block or model element in Simulink.

The code snippet that you have provided in the question is a correct approach to achieve this goal, and here is how you can use the ‘rmi’ functions effectively:

% 1. Specify the block to which you want to append a requirement 
blk_with_req = 'your_model/your_block_name'; 

% 2. Create a new empty requirement structure 
new_req = rmi('createempty'); 

% 3. Populate the new requirement with DOORS-specific fields 
new_req.id         = 'absolute_DOORS_object_URL'; 
new_req.type       = 'DOORS'; 
new_req.doc        = 'your_DOORS_module_name';      
new_req.description = 'Brief description of the new requirement';  

% 4. Append the new requirement to the existing ones for the block (here, ‘cat’ refers to concatenation) 
rmi('cat', blk_with_req, new_req); 

You can verify if the new requirement is added successfully or not executing the following command:

reqs = rmi('get', blk_with_req);

Refer to the following documentation links regarding different valid syntax for ‘rmi’ function:
