Not only has the typical system design grown in overall size to accommodate ever-increasing demands for functionality and performance, but these designs must fluently integrate analog and digital hardware, as well as the software that controls it. Successfully integrating and verifying that system components work in concert with each other often proves to be costly in terms of time, money and engineering resources. And, at the same time, there is increased pressure to reduce development cycle time. In order to keep pace with these new realities, new processes and development tools are required. In particular, the development and intelligent use of computer models of these complex systems—once considered a luxury—are becoming critical to the success of the overall development process.
