National Instruments Offers LabVIEW Interface for The MathWorks Simulink

Engineers Now Can Seamlessly Integrate a Wide Variety of I/O for Control Design

NEWS RELEASE -- Nov. 11, 2002 -- Enhancing the use of NI LabVIEW-based virtual instrumentation throughout the system design flow, National Instruments (Nasdaq: NATI) announced today the LabVIEW Simulation Interface Toolkit. With this toolkit, design engineers can link LabVIEW graphical development software with The MathWorks Simulink modeling and simulation environment to control and view Simulink model data and run Simulink models in LabVIEW. With the toolkit, design engineers can reduce product development time by quickly moving from simulations and models to validating and testing real-world prototypes.

The LabVIEW Simulation Interface Toolkit imports control models developed in Simulink directly into LabVIEW. The toolkit then automatically generates the LabVIEW graphical code that design engineers can use to verify their models with measurement hardware such as low-cost, industry-standard data acquisition and CAN interfaces. In addition, design engineers can use LabVIEW Real-Time and either PXI-based controllers or NI FieldPoint distributed I/O controllers to address high-end applications such as rapid control prototyping and hardware-in-the-loop testing.

"Engineers typically have struggled when moving their designs from modeling and simulation to real-world verification and validation," said John Graff, NI vice president of marketing. "Because of this difficulty, the market has requested the ability to use LabVIEW with products from The MathWorks to take advantage of the natural and intuitive approach of LabVIEW to bridge theoretical control design models to real-world implementation."

The LabVIEW Simulation Interface Toolkit also adds the power of the LabVIEW user interface to the Simulink environment. With the LabVIEW Simulation Interface Toolkit, design engineers can use LabVIEW-based user interfaces to intuitively control and view data within their control models. The toolkit gives The MathWorks' customers a licensed manner to control and view Simulink data under four National Instruments' patents currently at issue in a patent infringement lawsuit scheduled for trial in January 2003. National Instruments believes that use of the user interface features in Simulink® alone is similarly covered by the four National Instruments patents, but it is not licensed.

By using The MathWorks Simulink with the wide array of NI software and measurement hardware, design engineers can quickly validate numerous types of control designs and make necessary changes or improvements to their control algorithms. Rapidly producing and validating control design prototypes has grown increasingly important to design engineers in industries such as aerospace and automotive where product development cycles have decreased, but the pressure to ship new products to market more quickly continues to grow.
