Currently, the following workflows are possible with Simulink Requirements and Polarion:
1) Solution provided by MathWorks:
You can exchange requirements from external tools such as Polarion with Simulink Requirements using the industry-standard ReqIF format.
ReqIF exported from Polarion can be imported into Simulink Requirements to view and create traceability to the Simulink model. You can navigate back to Polarion from the requirement imported into Simulink Requirements. After importing Polarion items into Simulink Requirements, you can link the imported references with Test Cases in Simulink Test Manager to establish traceability. See the following documentation for Importing Requirements from ReqIF Files:
It is also possible to edit the requirements in Simulink Requirements and update Polarion with the changes using a ReqIF export from Simulink Requirements. Links to the Simulink model are also included in the export. See the following documentation for Round Trip Workflows with ReqIF Files:
See the following documentation from Siemens PLM on ReqIF Import/Export:
2) Solution provided by Siemens PLM:
Siemens PLM provide and support a tool for Polarion-Simulink integration called "Polarion Connector for Simulink". You can download it here:
The tool allows bi-directional traceability between Simulink models and Polarion REQUIREMENTS Work Items. You can navigate from Simulink model elements to their associated Polarion REQUIREMENTS Work Item and vice versa.
In August 2021, Siemens announced that there will be a new version of the Connector with improved features for use with MATLAB R2021b:
Please contact the vendor Siemens PLM for any queries or support regarding this tool.
