Hi Maj,
generally LabVIEW is a programming language that offers among other thing creating your own simulation code for any application.
I think your question aims more to circuit simulation. National Instruments offers also a software product called Multisim for circuit capturing and simulation.
Possibly that fit's also to your question, have a look on that link:
