ModelSim-Altera exiting

Hi all. I am trying to go through the tutorial (oem_tutor.pdf from Help>PDF files>Tutorial). When I get to the step : Loading the design into the simulator (on page T22), the simulator starts to do some things and then just exits. No warning or anything - it just closes.

What am I doing wrong?

I have version 6.1g

Kevin

btw, am I right in I read that Quartus can't nativly simulate VHDL??? Which means I must use ModelSim?

    The Quartus native simulator handles VHDL and Verilog source files just fine. It just doesn't support test benches. If you are using a test bench, you need a simulator like ModelSim.

    I would much rather use the internal simulator.

    I have v8.0 of the web edition. When I click on the button to specify a Simulator input file, no files show up in the dialog. Although it says it compiled with no errors (but with 4 warnings). The output files go into the project directory, right?

    If you can't tell, I am new to this. I am used to uC's.

    Thanks,

    Kevin

    The simulation input files are the stimulus files such as a vector waveform file. This is what the Quartus native simulator uses instead of a test bench.

    For functional simulation, the source files are used when you run "Processing --> Generate Functional Simulation Netlist". For timing simulation, the source files are used for the compilation; the simulation uses a postcompilation netlist.

    Ahhh. So, I have to make a stimulus file. I will give it a try.

    Thanks!
