LabVIEW instruments in transient simulation

[Everasia]

Hi,

I'm performing some tests with an InputOutput LabVIEW Instrument that I made myself (2 in/4 out) that basically implements a simple lookup table (on the basis of two DC voltage levels it perform a 2D interpolation and then sets the 4 voltage outputs accordingly).

In the interactive simulation mode everything works great.

However, if I try to run a transient simulation, the LabVIEW instrument does not respond, it seems to ignore the two inputs so it gives zero for all the 4 parameters. 

This suggests me that LabVIEW instruments are interactive-simulation objects only. Is it correct?

This would limit the benefits of this great tool! 

Can anyone suggest me a way to overcome this? 

I work with Multisim 11 and LabVIEW 2009.

Thanks.

Everasia,

Yes the custom LabVIEW instruments are used in interactive mode only.  What other things are you looking to do in Analysis -> Transient mode?  Expresssions, Post Processor data, etc?

Are you are trying to use LabVIEW as a type of I/O behavioral component?

Also, another possibility is using the Multisim API with LabVIEW (www.ni.com/labs) -

LabVIEW Multisim Connectivity Toolkit (Beta), this will allow you to create interactivity between LabVIEW controls and the Multisim simulation - you can adjust source inputs and measure probes and pause the simulation between steps.

If you would like to discuss the use case in more detail, please email me directly.
