Simulating the Design

To simulate the design, we will use ModelSim application from Intel/Altera. You can download the software for free form the Intel/Altera website. There is a test bench for this tutorial that is already created for you inside the GXFPGA\Examples\Quartus\GX3700\Tutorial_VHDL.  

Follow these steps to simulate the design:

1.      Open the ModelSim application:

ModelSim Main ModelSim Main Window

2.    Click Fileà Change Directory and choose the sim folder under the Tutorial folder. At this point the ModelSim should display the simulation pins:

3.  Click Toolsà TclàExecute Macro… and choose sim.tcl, and click Open. When ModelSim asks to close the current project, click Yes. The screen should appear like the screen below:
