Synchronous Simulation
In a synchronous simulation each of the simulated objects is updated with each (logical) clock tick even if there is no change … that is, all parts of the system are updated synchronously
The U-District Traffic Simulator is a synchronous simulator since the state of each light and car is updated with each advancement of the clock
Synchronous simulation is used for continuous simulations (wind over airplane wings, stars moving in a galaxy), and in other systems in which most elements change most of the time
