The first icon compiles the selected file, the second compiles all. You can also choose one of the following icons. The other option is to choose Compile from the Menu and click on Compile all. Right click on any file and select CompileCompile all. (2) Compiling Design Files and Testbench. Add all three files, by selecting all at once. When the next window comes up as shown in the next page, click on Add Existing File, and browse to the folder where the files are stored. In the "Project Location" point it to where your folder has been created. It is a four bit UP Counter, which counts till 15 and comes back to 0.Ĭlick on "File" "New Project". We will use these files to go through the tutorial. This subfolder will serve as your workspace.ĭownload the design files JK_ff.vhd and four_bit_counter.vhd, and the testbench (count_test.vhd). Within this folder create a subfolder called Counter". If the results are not as you expected, you could use debugging environment to track down the cause of the problem.įirst, in your Home drive (K:), create a folder named "ModelSim_tut". Assuming the design loads successfully, the simulation will run and you will see timing waveforms.

With the design compiled, you invoke the simulator on a top-level module (which is the Testbench, as you have instantiated your top level design entity in it). You can simulate your design if there are no errors. After creating a project and adding files to it, you compile your design units into it.

You select a destination for your project and give it a name. You start a new simulation in ModelSim by creating a working library called "work". In ModelSim, all designs are compiled into a library. The same steps apply when using ModelSim PE Student Edition on a home computer or laptop. The tutorial was prepared using Modelsim SE 10.0, which is installed on the lab computers. Note: This tutorial does not explain the design flow, i.e. Create a project and add your design files to this project. Timing Simulation of the design obtained after placing and routing.ġ. Post-Synthesis simulation of the circuit netlist. Functional Simulation of VHDL or Verilog source codes. It can be used for both FPGA & ASIC designs. ModelSim is a high-performance digital simulator for VHDL, Verilog, and mixed-language designs. You can also use WordPad, or any other text editor you are comfortable with for writing and revising your code.

Out of external editors we recommend Crimson editor. You can use the built-in source editor in ModelSim. Tools needed for simulation are: Text Editor and a Simulator. The respective simulations are called functional, post-synthesis, and timing simulation, respectively.

Simulation can be performed in three places in a project design flow: after coding, after synthesis, and after implementation. It is used to verify that the design performs as expected and performs required functions. Introduction Simulation is the process of applying stimulus or inputs that mimic actual data to the design and observing the output.
