Video Guide: How to get started with Xilinx ISE and VHDL
I posted this video guide on Youtube a couple of days ago, though I wanted to announce it in here too.
In this video tutorial I guide you thru how to make a counter application for the Basys2 board, which is an FPGA board from Digilent to those who are unfamiliar with it.
I will show you the required steps of setting up a project in Xilinx ISE, writing the VHDL code for the counter application, writing the pin constraints file (.UCF) and finally generating the bit-file for the Basys2 board.
This video tutorial was actually requested by a reader of the blog, so with this being my first video tutorial, I would like to show you that comments and requests ARE HEARD! 🙂
EDIT:
The Xilinx ISE project files for the tutorial can be downloaded here: Basys2_CounterApp.zip
Thank you very much for your help ! Your video is a perfect tutorial. I’m french’s teacher, can I use your tutorial for my students please ?
@nat
Hi Nat.
Sure you can.
Have you seen the most recently uploaded about getting started with Xilinx ISE and VHDL? That video is a bit less advanced than this one, as I just show how to blink an LED.

hi Thank you very much for this tutorial its very helpful
can you please post the project files ?
@jeen
The project files can now be downloaded from here: Basys2_CounterApp.zip
Great tutorial, just what I needed to get started ! Thanks for taking your time to share this !
Hi,
great video. I’ve just started to learn Xilinx ISE using VHDL. I’m having problem in stating a new project. whenever I tried to browse for working directory/project directory, software starts to close and a massage “_pn.exe has stopped working” appears. whats the solution
@Nigar Sultana
Can you try and take a screenshot of the error, as I am not aware of the issue.
Hola, me parece genial el vÃdeo, felicidades! Muchas Gracias.
Disculpa para encender los displays solo necesito cambiar el archivo .UCF y poner la localización de los segmentos del Display?. Muchas Gracias 🙂
Hello, Congratulations for the video and thank you very much.
Excuse me, I have a question about of displays, I need only change the .UCF for turn on the displays? Thanks 🙂
@Enrique
I am not sure I understand your question.
The .UCF file is used to describe which pins the internal FPGA VHDL connections should be routed to. So in this case we need to tell the synthesizer where the CLK input is located and where the 8 LED outputs are located.

I felt so comfortable around project navigator within 2 hours because of these video. please i have a question, how to i use adept after programming it with my bit file. how do i do that? thank you very much
@roberto
Hi Roberto.
Thanks for the kind words.
After you have finished synthesizing and “Generate Bitstream”, you should be able to find a *.bit file inside the project folder.
By installing the Digilent Adept program, which requires you to have a Digilent programming cable as well, you can program the bitstream into your Xilinx FPGA thru JTAG.
Regards Thomas
hi Thomas
can you please help me explain it much better, am confused about the JTAG part and the codes, and the codes for the counter and clock module does not generate the bit stream.. it goes error after implementing if refers me back to the ucf file. thank you very much
Really the video was very much helpful
Thank You Mr. Thomas for your generous work
Do You have any tutorial for VHDL Language
I mean tutorial on syntax and semantics of VHDL
Regards
@roberto
Hi Roberto.
Before you can generate a proper bitstream you need to make sure that your ucf file is correct, as this file tells the program which pins to route the different labels in your VHDL to.
When this is done, you should be able to press the “Genereate Bitstream” to get a .bit file.
This file should then be programmed into your FPGA by a JTAG programmer supporting FPGA’s, in this case Xilinx FPGA’s. In my case I am using the Digilent Adept programmer, but a BusBlaster could be used as well!

@Anis Kirkire
Dear Anis.
Thank you for your comment.
I unfortunately don’t have any plans for new VHDL videos in the following months due to a very busy schedule.
If you could be a bit more specific about your tutorial need on the syntax I might be able to pin-point you to some usefull external resources.
Regards Thomas
@Thomas Jespersen
I want to learn VHDL language i.e
how to write a code for particular hardware
& also to know the strength of XILINX Project Navigator & PlanAhead
that where and how it is used
Thank You for Responding to Previous Comment
Sincere Regards

@Anis Kirkire
Can you help me out in writing the VHDL code for
“Falling Edge Triggered Adders & Multipliers”
Sincere Regards,
Anis Kirkire
@Anis Kirkire
To implement and use falling-edge triggers you will have to use the following statement within a process:
-- do the adder or multiplier calculation inside here
end if;
Hello,
I wanted to ask one thing.I am new to Xilinx and spartan. I am unable to identify my pins numbers on the board with yours. My Board is Spartan 3 with device XC3S200 and package FT 256. I think that my .UCF file will have different pin numbers from yours. Can u plz guide me with this.Thanks alot
@Saher
Hi Saher.
Which board do you have? Please make sure it is also the Basys2 board and not another Xilinx Spartan 3 based one.
I am not aware that Digilent should have made any changes to their board, so our UCF file should still fit your board as long as you have a Basys2 board.
Regards Thomas
@Thomas Jespersen
I was using Spartan 3 and i was able to figure it out.Thanks.
excuse me … sorry my question deviate from the above concept.
I want to ask, how to make coding vhdl adc in spartan 3e and the data is displayed to LED?
sorry I am beginner in vhdl FPGA coding.
please its support ..
@wahyu
You need an external ADC converter chip that you have to connect to your FPGA.
Depending on the chip you can either read the data thru a parallel interface or a serial interface. For an easy solution I would recommend an ADC with a parallel interface though the cheaper ADC’s comes with a serial interface such as SPI or I2C.
sir,
i am a research scholar and working on “watermarking for medical images” and have use FPGA(DON’T know how to) and new to Xilinx System generator software. There are some question, please assist me.
1. is this not inbuilt in MATLAB?
2. WILL i have to download it from somewhere else?
3. how will i start FPGA?
4. Xilinx System Generator, ISE,FPGA all are different
@Ankur Rai
Hi Ankur.
If being new to FPGA’s going straight for image processing might not be an easy task.
Please find the answers to your questions below:
1. FPGA’s are not computers. They are programmable logic why you would have to generate a microprocessor or similar if you want to execute computer-similar code on it. So NO, MATLAB code is not supported – but you might be able to port MATLAB code to an FPGA by the use of Xilinx’ new High-Level Synthesis tool.
2. Have to download what? To get started you would have to install the Xilinx ISE or Xilinx Vivado software, which can be found here: http://www.xilinx.com/support/download.html
3. I would recommend you to start learning the basics of logic and VHDL (or Verilog) programming. You could start out by trying the steps explained in my video above (this post).
4. The Xilinx System Generator is a higher level that will help you generate the lower parts of the VHDL code to get a specific system up and running, by the use of some built in Xilinx blocks. You could use this, but I would still recommend you to get a basic understanding of the FPGA before trying out these more advanced features.

thanksssssssssssssssssss
i need more exemples plz
thank you so much for this tutorial can you make for us more exemples i want to know more about programming FPGA by VHDL
Hi, Thomas,
Thanks for such nice explanation of Xilinx ISE VHDL example. I have to program FPGA Spartan 3 Device XC3S200. In your tutorial you mentioned to install BASYS 2. Is this software board specific? and if I do not know the provider, which software I should install. Please help.
Dear Thomas, Could you please respond. Thanks
Is there is any software to generate output on MacOS?
@Rishabh Garhewal
No. Xilinx software tools are only officially supported on Windows and Linux.
