Real-time simulation refers to a method of modeling and simulating systems in a way that allows the simulation to respond instantly to changes in inputs or conditions, providing immediate feedback. This capability is essential for applications that require timely decisions, particularly in automotive systems, where performance and safety are critical. By integrating real-time simulation into model-based systems engineering, developers can better analyze, validate, and refine complex system designs.
