Running previous version models
Please note that when you open a system created using an older version of the software, the system will detect that it is an outdated model and lead you through a compulsory model update assistant process. A new executable will be created when you switch to Simulation mode, and when you save it, the entire model will be converted to the latest software format.
It is important to remember that models created with the latest software version cannot be compatible with previous versions of the software.
