Simulation Techniques

Model-Based Development of Real-Time Systems Integrate M&S in every step of the development of embedded RT systems. M&S-based architecture: models used in simulation are the target for end products. Rapid prototyping Encourages reuse Cost-effective Prototype tools readily available

Model-Based Development of Real-Time Systems - Robot prototype - 6 man-hours to develop the whole controller, test, modify, retest - Simulation-based solution (model controls the robot) - Motor controller - Multi-motor controller

Model-Based Development of Real-Time Systems - Fully developed controller with sensor feedback - Remote control application - Model-based applications - Enhanced facilities for testing - Model execution: guaranteed to be correct (formal specification)
