The total cost may vary from starter to mid range to enterprise level apps in both cases.

All in all, the total cost of ownership in the both cases is almost the same and may span over a period of 7-10 years, though you may have to pay a higher perpetual license fee upfront.Additionally customers using premium support services must pay an extra fee. Recurring cost is greater as customers are required to make monthly payments as a subscription fee.Upfront cost for customization and integration is less compared to perpetual license cost because there is not much flexibility with SaaS systems in this area.
Subscription pricing model is more common with Software-as-a-Service (SaaS) apps. Ideally, customers are required to pay a recurring monthly fee until a specific period for using the tool. The payment is made either on a per user basis or subscription basis.

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.
