Modeling and simulation are especially valuable for testing conditions that might be difficult to reproduce with hardware prototypes alone, especially in the early phase of the design process when hardware may not be available. Iterating between modeling and simulation can improve the quality of the system design early, thereby reducing the number of errors found later in the design process.
Common representations for system models include block diagrams, schematics, and statecharts. Using these representations you can model mechatronic systems, control software, signal processing algorithms, and communications systems.
