System design teams can realize significant and measurable improvements in time to certification, time to market, quality, and costs using a model-driven development flow and including test considerations as a first-class element of the system design process. For the system engineer, a model-driven tool flow provides a virtual environment for complete system engineering. For the test engineer, a model-driven tool flow provides a virtual environment for test development. Examine how the SystemVision/SVX virtual prototyping platform, integrated with LabVIEW, is used to develop systems and test them early in the design cycle.
