What are the tools available in ModelSim?

ModelSim is a multi-language environment by Mentor Graphics, for simulation of hardware description languages such as VHDL, Verilog and SystemC, and includes a built-in C debugger. ModelSim can be used independently, or in conjunction with Intel Quartus Prime, PSIM, Xilinx ISE or Xilinx Vivado.

How do you use a ModelSim?

1. In order to run your simulation, you need to create a project. Click File -> New -> Project.
2. Click on Add Existing File as shown in the picture to the right.
3. To start your simulation, click on Simulate in the Menu Bar, then click Start Simulation.
4. Here is your waveform window.

How do I run QuestaSim?

If you have not already done so, perform Setting Up a QuestaSim Project with Command-Line Commands….To run a macro script:

1. From the Mentor Graphics® QuestaSim main window, chose Execute Macro.
2. In the Execute Do File dialog box, locate your QuestaSim macro file (. do).
3. Click Open.

How do you run a test bench?

To run the simulation right click on the testbench module that you want to simulate, in this case “mux_testbench”, i.e. right click mux_testbench > simulate, or simply double click on it.

How do I see objects in ModelSim?

Viewing Variables in Modelsim In Modelsim, the Objects window never displays variables. Variables can be enabled by first showing processes. This is done by right clicking on the design that you want to view the variables for. Go down to Show, and check that Processes are being shown.

How do I run a Verilog code in ModelSim?

ModelSim & Verilog

1. 1 Environment Setup and starting ModelSim.
2. 1.1 Create a working Directory.
3. 1.2 Source the setup file and run ModelSim.
4. 2 Create and compile Verilog modules.
5. 2.1 Create a new project.
6. 2.2 Write a Verilog file.
7. 2.3 Compile the Verilog file.
8. 2.4 Create a testbench.

How does a test bench work?

The testbench simply reads the test vectors from the file, applies the input test vector to the DUT, waits, checks that the output values from the DUT match the output vector, and repeats until reaching the end of the test vectors file.

What is the need of test bench?

A test bench or testing workbench is an environment used to verify the correctness or soundness of a design or model.

What is the purpose of ModelSim?

ModelSim is a verification and simulation tool for VHDL, Verilog, SystemVerilog, and mixed- language designs.
