There are two opportunities to get a legal free Modelsim license: If you are a student, you can get a free student edition at Mentor website link. Modelsim is one of the best multi-language HDL simulator developed by Mentor Graphics.

In the Execute Do File dialog box, locate your QuestaSim macro file (.

From the Mentor Graphics® QuestaSim main window, chose Execute Macro.

If you have not already done so, perform Setting Up a QuestaSim Project with Command-Line Commands….To run a macro script: setup.sh and follow the installation GUI.

Change the fist line from #!/bin/env bash to #!/usr/bin/env bash.

Open up the setup.sh file in an editor.

Open up a terminal and change to that directory.

Installation Steps for Quartus and ModelSim

To start your simulation, click on Simulate in the Menu Bar, then click Start Simulation.

Click on Add Existing File as shown in the picture to the right.

In order to run your simulation, you need to create a project.

This will run your simulation for 100 nanoseconds. To run the simulation, click the Icon with a little piece of paper and a down arrow next to the 100 ns time. All of the test bench signals have been added as signals your can monitor. You can also click and drag signals to the waveform window from other windows in Modelsim. To do this, right click on and_gate_tb in the sim window and click Add Wave. In this example, we will monitor all of the signals in the test bench. The next figure shows you what your waveform view looks like, but first you need to add some signals to monitor. It shows how your module reacts to different stimulus. The waveform view contains waves (binary 0's and 1's, hexadecimal digits, binary digits, enumerated types, etc) for all of the signals in your design. Now, the majority of the time that you use Modelsim will be spent looking at the waveform view. Modelsim Simulation Window - Simulation ReadyĪlmost there! The simulation is ready and waiting.

You are greeted with a window that looks like this

Copy the code below to and_gate.vhd and the testbench to and_gate_tb.vhd. The VHDL code creates a simple And Gate and provides some inputs to it via a test bench. The actual code is not important, so if you are learning Verilog that's OK! You don't need to know VHDL for this tutorial. The code that we will be simulating is the VHDL design below. Clicking on an existing license request link from your browser bookmark or from a link posted on the web will not work. At the end of the installation you must select Finish and a browser window will open with the License Request form. Note that you will need to request a license from Mentor Graphics. Perform the installation with the default parameters. Let's get started.ĭo you have Modelsim downloaded and installed on your computer? Get it here. Did you forget an if statement somewhere? Did you remember to give every possible case statement assignment? These are the types of errors that are very easy to make when you do not simulate your design. A great simulation will exercise all possible states of the design to ensure that all input scenarios will be handled appropriately. Simulation allows the designer to stimulate his or her design and see how the code that they wrote reacts to the stimulus. Simulation is a critical step of designing FPGAs and ASICs.

This tutorial explains first why simulation is important, then shows how you can acquire Modelsim Student Edition for free for your personal use. It is the most widely use simulation program in business and education. Modelsim is a program created by Mentor Graphics used for simulating your VHDL and Verilog designs.
