Hi vishalmahulkar,
Typically you would use the Simulation Model Converter to convert statecharts developed with The MathWorks, Inc. Stateflow® application software into statecharts usable within the LabVIEW Statechart Module.
A few troubleshooting questions:
Have you been able to get any other external models to run in LabVIEW using the Model Interface Toolkit?
Do you see any warnings when you compile your model?
What software versions are you working with? You may want to check to make sure everything is compatible.
The link below discusses some things to be aware of when working with the Simulation Model Converter:
