Now, the majority of the time that you use Modelsim will be spent looking at the waveform view. Modelsim Simulation Window - Simulation ReadyР”Р„lmost 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.Р”Вo 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.

By default, Altera software expects AHDL source files to have a. In contrast to HDLs such as Verilog and VHDL, AHDL is a design-entry language only all of its language constructs are synthesizable. AHDL has an Ada-like syntax and its feature set is comparable to the synthesizable portions of the Verilog and VHDL hardware description languages. It is supported by Altera's MAX-PLUS and Quartus series of design software. AHDL is used for digital logic design entry for Altera's complex programmable logic devices (CPLDs) and field-programmable gate arrays (FPGAs).
