Whether it's single microcontrollers handling motor control or an automobile assembly line containing multiple robots, you can be sure mechatronics is in the mix. Simulating such complex systems allows developers to build without having the hardware in hand. This is critical when some or all of the hardware doesn't exist, but becomes even more valuable when considering "what if" scenarios. However, two major issues continue to crop up: speed and complexity. Larger systems, more detailed simulation, and a host of other factors push the need for high-performance host development systems. Tradeoffs between simulation speed and the level of accuracy must often be made because of available resources. Faster processors always help, but the trend toward multicore systems actually works in favor of simulation because the systems being simulated are distributed as well.
