The Time-Triggered Paradigm

The time-triggered paradigm encompasses a set of concepts and principles that support the design of highly dependable hard real-time systems. The concept of a sparse time base enables a consistent view of events and supports the identification of a global system state. As a prerequisite, clock synchronization is necessary across the distributed system. A concise description of interfaces in both, the value and the temporal domain supports a two-level component-based design approach. For dependability, fault-tolerance can be implemented by redundancy and fault containment concepts. The time-triggered communication provides a predictable timing behavior with guaranteed timing assumptions under full load and faulty conditions.
