Quartus II Simulator Output driving Simulator Input

[Altera_Forum]

All, Quick question:  

Quartus 9.0 Simulator: (the simple simulator that I can physically see and edit the waveform on the screen, and then rerun it and see how it effects the output)  Can I have the output of one simulator file drive the input of another simulator file? There is the Simulation Input that can have multiple files (*.vwf), but that doesn't seem to do anything that I have noticed. Is there documentation stating what the Multiple Files input does for the Simulation?  I want to simulate the output of PLD-1 driving the inputs to PLD-2. I have PLD-1 done and complete, now I want its output to be the inputs of PLD-2.  Any ideas?  Keith
