leongchuan,
When using the LabVIEW Simulation Module and the Simulation Loop structure you simply wire the output to a previous element in your diagram. The attached jpg file demonstrates how to do this.
Most of the example files included with the Simulation module also demonstrate how this works. You can find these examples in the C:\Program Files\LabVIEW 7.1\examples\simulation\ folder.
