How to Build a Mixed-Criticality System in Industry?

In the last decade, the rapid evolution of diverse functionalities and execution platform led safety-critical systems towards integrating components/functions/applications with different ‘criticality’ in a shared hardware platform, i.e., Mixed-Criticality Systems (MCS)s. In academia, hundreds of publications has been proposed upon a commonly used model, i.e., Vestal’s model. Even so, because of the mismatched concepts between academia and industry, current academic models can not be exported to a real industrial system. This paper discusses the mismatched concepts from the system architecture perspective, with a potential solution being proposed.
