Event-Based Modeling

“Mach 2 travel feels no different,” a passenger commented on an early Concorde flight. “Yes,” Sir George replied. “That was the difficult bit.” – Sir George Edwards, co-director of Concorde development – quote taken from “Concorde, New Shape in the Sky.” The ability of design engineers to predict massively complex systems often relies on event-based and primarily digital simulation. There is a trade-off between speed and accuracy inherent in this approach and understanding that trade-off is essential for mixed-signal designers. Most digital designers take this efficiency completely for granted and have no understanding of this – much like the passengers on the supersonic Concorde aircraft. The opposite could be said ...
