Hello,
As of right now, LabVIEW does not interface directly with the Altera software. However, if you can access an Altera DLL or library that controls and displays the inputs and outputs for the circuit, you could call and control that from a LabVIEW application. Please see the "Using External Code in LabVIEW" manual for more information on this process:

As well as this site:

Hope this helps!
