This paper describes the technologies required to improve test quality and reduce development cycles. Comprehensive testing is critical for many mechatronic systems; however, mechatronic system design creation and test development are often at opposite ends of a project’s schedule. Benefits accrue in improved system quality and on-time delivery when design and test are pursued concurrently. Recent advances in modeling, simulation, and test technology provide the ability to link system design to system test well in advance of prototype availability. Mentor Graphics SystemVision conneXion tool links the power of a virtual prototyping environment with the flexibility of LabVIEW’s virtual test environment. The result is better test programs, improved system quality, and reduced development cycles.
