NI Rolls Out LabVIEW Simulation Interface Toolkit 2.0

10/30/2003 - National Instruments announced the LabVIEW Simulation Interface Toolkit 2.0, an add-on that links the NI LabVIEW graphical development environment with The MathWorks Inc. Simulink modeling and simulation software. With this toolkit, design engineers build custom user interfaces to interactively verify Simulink models and easily deploy these models to real-time hardware for control prototyping and hardware-in-the-loop testing, helping them deliver new products to market faster.

"The LabVIEW Simulation Interface Toolkit offers a quick route to implement hardware-in-the-loop test systems for the control algorithms we develop in Simulink," said Paul Ingleby, senior servo systems engineer at BAE Systems. "This toolkit has significantly reduced testing time and has become an important part of our servo design process."

The LabVIEW Simulation Interface Toolkit includes a connection manager that engineers can use to create custom LabVIEW-based graphical user interfaces that connect to parameters and output of Simulink models. Engineers can incorporate their application knobs, dials, gauges and graphs into a single, comprehensive interface to easily verify their simulation models. In addition, they can implement batch simulations to validate Simulink models with a wide range of test parameters.

Engineers use the same custom user interface to connect to a real-time PXI system to easily transition from verification to hardware prototyping. With just a few mouse clicks, engineers can download the LabVIEW test application and Simulink model onto real-time PXI hardware to quickly determine how the prototype model performs when connected to a real system. By seamlessly deploying custom control models to real-time hardware, engineers can identify flaws earlier in the design flow, greatly reducing overall development time.

By using LabVIEW with The MathWorks, Inc. Simulink software, engineers have access to the widest array of hardware options for downloading the Simulink models. In addition to real-time PXI systems, they can download Simulink models to PCI plug-in real-time boards and NI Compact FieldPoint for embedded or distributed prototyping and hardware-in-the-loop testing.
