You can run the Mentor Graphics ModelSim-Altera software, provided with the Quartus II software, from the ModelSim-Altera interface or with command-line commands.

Modelsim is one of the best multi-language HDL simulator developed by Mentor Graphics. Modelsim is essential for simulation of hardware description languages such as VHDL, Verilog and SystemC. Modelsim includes also a powerful C debugger. ModelSim can be used independently or in conjunction with Altera Quartus or Xilinx ISE/Vivado. ModelSim-Altera Starter Edition (MSSE); ModelSim-Altera Edition (MSAE). The two differences between ModelSim-Altera Starter Edition and ModelSim-Altera Edition are that simulation performance are best with MSAE and with the MSSE you cannot compile more than 10,000 lines of code. There's of course another difference: MSSE is free, MSAE is paid. Aug 09, 2021 ModelSim (modelsim.exe). ModelSim is a program recommended for simulating all FPGA designs (Cyclone®, Arria®, and Stratix® series FPGA designs). ModelSim has a 33 percent faster simulation performance than ModelSim®-Altera® Starter Edition. ModelSim apears in two editions Altera Edition and Altera Starter Edition. My design successfully compiled on Quartus II v.11.0 sp1, and i try to simulate it using Modelsim-Altera web free edition 10.0 C. I open a new project (.mpf)on modelsim Altera V. 10.C and add the (.vho) files from simulation directory of the design ( I use this method along the different stages of. EDG Quartus/Modelsim Tutorial. This tutorial is for use with the Altera DE-nano boards. There are a number in the eshop. See Mary if you cannot find one. In this tutorial, we will program the DE-nano board, to be a simple 3 bit counter. The leds labelled led1, led2 and led3 will be the outputs. The values will change each time Button1 is pushed.

To set up a ModelSim project with the ModelSim-Altera interface:

Modelsim Altera Student Edition

1. If you have not already done so, set up the ModelSim-Altera working environment.

2. Start the ModelSim software.
3. To specify the project directory:

   1. On the File menu, click Change Directory.

   2. In the Directory Name box, type the path to the project directory .

      or

      In the Look in list, select the project directory.

   3. Click Open.

   Note: If you are performing a functional simulation, the project directory is usually the directory that contains the design files. If you are performing a timing simulation, the project directory is the <project directory>simulationmodelsim directory or the location you specified in the Output directory box of the Simulation page in the Settings dialog box.

5. To create a new work library:

   1. On the File menu, point to New and click Library. The Create a New Library dialog box appears.

   2. Under Create, click a new library and a logical mapping to it.

   3. In the Library Name box, type the library name.

   4. In the Library Maps to list, select the work library.

To set up a ModelSim project with command-line commands:

1. If you have not already done so, set up the ModelSim-Altera working environment.

2. Start the ModelSim software.

3. Change to the directory where the ModelSim libraries are located after they are compiled.

4. To create a new work library, type the following command at the ModelSim prompt:

   vlib work

   ModelSim compiles the design files to library work by default.

5. To change the default library, type the following commands at the ModelSim prompt:

   vlib <user defined library>

   vmap work <user defined library>

7. Before performing a functional or timing simulation, you should map to libraries and compile design files with the ModelSim-Altera software.

To continue the ModelSim-Altera flow, you can perform a functional simulation with the ModelSim-Altera software, and then you can perform a timing simulation with the ModelSim-Altera software.
