This is excellent. You explain the obvious things you need to know but no-one ever seems to bother doing! I've learned more from these 15 minutes than the countless hours and pages and videos I've endured :) Thank you.
This was exactly what I was looking for as a first time user of Vivado. Thanks
Great Tutorial. Very well explained. Not too fast to be able to follow, so no need to pause, but a lot of information in a very short time. Also you have a pleasant voice that doesn't loose a brains attention. I hope you will make more Zybo tutorials. As you see, many people hope so.
This is gold, finally a tutorial of vivado+vhdl that is not just the simulation
Nice explanation through step by step...., do more for educate biggners. It very helpful. Thanks a lot..
best tutorial ever
Older video (2021 now), but was still a great help as a first introduction to Vivado and the Zybo-Z7 board! Thanks so much.
this is really helpful to start using vivado. thanks a lot!!
Thanks a lot for your instructive episode as a clearer on youtube.
keep going to build well and advance the level project with VHDL or Verilog as a language.
Fantastic beginner tutorial! Finally allowed me to get started!
Great tutorial Sara, you’re clear, succinct and fun to listen to. I look forward to viewing more of your videos! :)
Best tutorial on the basics thanks !
So I just tried this on an ARTY Z7 board and it worked!!! Thank you
Saw a ton of videos but yours was too perfect..Thanks
Used the same steps to do my own first project. Had to grab the XDC for the Z7 board but all worked well! thanks, Thumbs up from me!
Very nice explained. Thanks Sara :)
Very good. Sara!
Good work. Very helpful. Thanks for making this video.
Well done! I went through the same process but with the Zedboard. I ran into some trouble when synthesizing and generating the bit stream due to differences in the .xdc files between the Zybo & Zedboard. For some reason the Zedboard xdc file reduced all of the iostandard expressions to one for each "bank." I wrote out the iostandard expressions for each switch and LED the way you did and it worked fine.
Great tutorial, paced nicely. Well done & thank you! (looking forward to more :-) )
Very Very Helpful! Thank you!!
Best tutorial by far. Thanks a lot.
Thanks loads. Same do, but with an Arty. Only difference was that the sum and carry outputs didn't get buffered - it generated only the xor and the nand gates. Otherwise everything followed thru to sw-ing and led-ing on the board as hoped. I mean expected.
Extremely nice tutorial. That helped out a lot.
great tutorial, so helpful, u made it so easy and clear thanks
Really clear tutorial Sara - thanks a lot!
very use full tutorial, thank you Sara.
Very useful and clear!
Helped me alot and i love your voice
I am not able generate the bit stream. It shows error.
Very well done video tutorial!
Thank you for the tutorial!
Very good tutorial!
how to implement n bit adder in zybo board because zybo board has only 4 sliding switches and 4 leds can you explain how to implement n bit adder using zybo board
Hello Sara, I am getting following error, could you please let me know what mistake I did?
[Board 49-26] cannot add Board Part digilentinc.com:arty-s7-25:part0:1.0 available at C:/Xilinx/Vivado/2015.4/data/boards/board_files/arty-s7-25/E.0/board.xml as part xc7s25csga324-1 specified in board_part file is either invalid or not available
Thanks in advance.
Hello Sara! Thanks for the great video! A small question... What version of Vivado are you using? Is the lab edition enough to play with the Zybo Board? Thanks in advance!
+Jose Martins I'm using the 2015.2 Design Suite edition. I haven't tried it with the lab edition, but I don't see there being any problem.
Hello Sara! Thanks for the tutorial..
I'm new to this, I need to use the zybo and USB OTG port for connecting a keyboard, as I can do with VHDL ?? .... I do not find you need in the ZYBO_Master.xdc, Can you help me with this?
Awesome Video
Thank you so much !
Hello Sara. Thank you for the great tutorial! I just started a class using a ZYBO and keep running into weird errors. May I contact you with questions?
nicely explained
Hello, Thanks for the great video! Now i am doing a 2 bit ripple adder using the half adder.
i have create an half adder as you did in the video. Would you please what is the next step to create in Vivado that create a full adder using the half adder. i know the logic, but i just do not know what to do next. Thanks so much
How do I assign 2 inputs in my constraint file when each input is 16 bits?
Very useful.
great tutorial ..!
Vey useful Tutorial Sara. Where are the next tutorials?
+Dr. Talal Bonny I plan on putting up a few more by the summer.
hi, thank you for the video, please if i want to turn on LEDs of a Nexys board, but I don't have it, i wanna do the simulation, how can I do?
hi
i have zedboard zynq 7020
i write simple VHDL code.
I want to send this code to flash or SD card and run it on the board. but i can't it
How can i solve it?
Thanks in advance
thank you.
why u dont need to write a testbench?
Hey Sara, make some more tutorials
Pliz haw i can mak link bitween hard and soft using buses
Hi Sara,
Thank you very much for the video. I was wondering that why you didn't set up debugging for the ILA file. When I want to program my device, it asks for the debugging file.
+havva erdinç Debugging is an optional process. I plan on putting up a tutorial video on using the debugging feature soon.
This will be great, cause vivado warns me that there is unconnected pins on ILA. This is surprised me. When I want to program my device, it asks me a debugging probe file. Then I thought that it as an obligatory process. I will try this example myself.
You said something about mismatched upper or lowercase identifiers causing errors. According to VHDL PDFs I've read the VHDL compiler is actually case insensitive.
Yeah I've had a few people say they were able to get away with case miss-matches. When I was running through the lab, I seemed to have issues with case. It's possible newer versions are case insensitive, or I made some other mistake that was resolved when I fixed the case and didn't notice. I haven't had the chance to check as I don't currently have the software installed on my computer. I''d recommend keeping things in the same case anyways for consistency and to prevent any confusions.
As an extreme example in Vivado 2017.1 (64-bit) build 1846317 the following two snippets are equivalent (both compile and produce same design):
-- Allow connection of data bus as output during write operations or disconnected
-- (high-Z) otherwise allowing other devices to use data bus while the CPU is halted.
db_ogate: process(nDBen,DBwe,regbus) iS
begin
if ((nDBen and DBwe) = '1') then
d
Define module window ,,, how u open up it 2:20
@3:40 or so: are you sure that VHDL is case-sensitive when it comes to ports? Because at least for signals and variables, identifiers are case-insensitive.
That's been my experience with this version of Vivado.
Nah. Just tested on Vivado 2016.4. This piece of Code (look at S, s):
entity test1 is
port(
S : in bit_vector(1 downto 0);
A, B : in bit;
Y : out bit
);
end test1;
architecture BHV of test1 is
begin
with s select Y
Hm, the most recent version of Vivado I've used is the 2015.2 version. I'll have to double check, but I remember having issues with case sensitivity regarding the port names.
how to create testbench file
Nice tutorial. VHDL is NOT case sensitive, however.
when i right click on A input in simulation there is no force clock value just cut, copy ....etc. so i cant set forge clock value. Does anyone has any idea why?
+Hüseyin Temizkan It depends where you're right clicking. You have to click on the port in the name column to bring up the right dropdown menu.
this video is for simple combinational circuits, for sequential circuits(for example practical vending machines ) there is clock(as an input ), so how can we give that input to FPGA(in .xdc file)?
+Ramakrishna Kannoju There's a specific pin on the board you can use, L16. In the xdc file, your clock input should connect to this pin.
+Sara Fagin Thank you,
first I tried a simple counter(with reset and clk s inputs), I didn't get the counting sequence.
can I have your email id? so I can seek some help.
+Ramakrishna Kannoju
Sure, you can reach me at fpga.tutor@gmail.com with any questions.
Do you need the vivado license to do that ?
To install and run Vivado you do need a license. If you already have it installed and the license has expired, you should be fine as long as you don't update it.
...i cant open it again if i closed the window??? so unfriendlly
that means i cant change my entity name......
So the window is really just for convenience. Once you've finished with the creation wizard, you can edit everything in the file still, just manually. Including changing the Entity name, adding modules, inputs and outputs. The entity name doesn't have to actually match the file name.

What?? Women work on embedded systems? You sure are a rare breed
I really want to learn this VHDL for VLSI Technology. I want to do Ph.D. in VLSI. Please help me and give me your mail-id. This video is very helpful.
