Model-Based Engineering Approach for System Architecture Exploration

Abstract: Safety-critical systems may contain a large number of functions having different security/safety levels and must ensure a continuous operational state. It is of prime importance to avoid errors propagation between system functions. One may identify two main solutions to tackle that problem. The first and classical solution relies on the federated architecture where different hardware nodes, each one executing one or several functions having the same security/safety level, are interconnected using communication channels. The second solution emerged recently and leaded to the definition of the integrated architecture where a same hardware node is able to execute several functions having different security/safety levels
