After that, we can click on run for a finite among of time, in this case, 120 ns. The signal to be plotted should be dragged into the wave diagram to see them.

Now everything should be ready for our first simulation! We click on the left panel on вЂњRun simulationвЂќ and the simulation view will open. The setting should be checked and changed. This is made in Simulation settingsвЂ¦ Right-click on the word вЂњSIMULATIONвЂќ. Then we choose вЂњLet Vivado manage the wrapperвЂ¦вЂќДЄfter the wrapper is created, we to need to say to Vivado which file is our top level. In this case, we donвЂ™t have yet a constrain file, but Vivado requests it.ДЇor that we create an HDL Wrapper by right click on the block diagram sources: This wrapper is a file that connects the output/input port of your block diagram to the physical pin described in the constraint file. To be able to simulate, Vivado needs a Wrapper over the block diagram. For that right-click on the diagram and then select вЂњAdd ModuleвЂ¦вЂќДЄnd then, we can connect the blocks with each other, just wiring the signals. The created modules should be added to the block diagram to interconnect them. The following example of Stimuli can be copied as a reference: `timescale 1ns / 1psДЄ = $urandom_range(0,1) //random value between 0 and 1 For this a new module named вЂњStimuliвЂќ as before is created.

In this example I wrote a simply asynchronous and-gate in Verilog:ДЇor the simulation, a stimuli block or wave generator will be needed to stimulate your modules under test, in this example the and-gate. You can remove it or leave it smaller as I did. The automatic template for an RTL module in Vivado has a very big header. By double click on the sources, a window will open.

Now, we are going to add some code in the module. But this can be done later by code (faster and easier), so for now we skip this step pressing OK.ДЄnd when a new window is prompted, press Yes, we are sure! Vivado will ask you to configure the inputs and outputs. Give a name to the RTL module, select Verilog as file type and then press OK and then Finish. On this diagram, all your modules are going to be placed and tested.Д¬lick on вЂњAdd sourcesвЂќ to create the modules: Start by creating a new block diagram to be the top of the testbench. But I would suggest connecting a second screen to work more efficiently. The fast way is to double click on the top bar of each window to maximize it (where the red crosses are) also the maximize button works identically. You will want to maximize temporally the windows, especially the block diagram. For small laptop screens (as mine), it is a bit awkward to show all the information and work comfortably. You will get familiar with each window, when you spend some time in Vivado. If desired this can be chosen later.Д¬lick вЂњFinishвЂќ and the new project will be opened. If you start an empty project, you donвЂ™t have any source to add to the project, therefore check the box вЂњDo not specify at this timeвЂќ.ДЄs we want to only simulate, we are not going to select any hardware. The type of the project should be an RTL project. In this example, I chose C:// as project location. Give a name and a project directory to store all the related files. It will take a lot of time, around 1 or 2 hours.Д¬reate a new project with the assistant with File>New ProjectвЂ¦

The download-file is not so big, because during the installation it will download the necessary files. For that you will need to register in Xilinx and then get the вЂњ Vivado HLx 20XX: WebPACK and Editions Self Extracting Web InstallerвЂќ.

If you donвЂ™t have it, download the free Vivado version from the Xilinx web.

In this small tutorial, I am going to explain step by step how to create your testbench in Vivado, so you can start a Vivado Project, begin to program and boost your Verilog or VHDL learning. It is very common with the students, who are trying to learn a new programming language, to only read and understand the codes on the books or online.Д«ut until you donвЂ™t put hands-on and start typing your own small programs, compile them, find errors, simulate, etc you will not get the experience to write your own codes and therefore to learn how to program a new language. How to start a new Vivado project to create a testbench for programming with Verilog or VHDL languages.
