Icarus verilog + GTKWave installing and running | Free software for verilog HDL
HTML-код
- Опубликовано: 22 янв 2021
- Iverilog is a free software where we can compile & check the waveform of our design , I have explained in the video , how to download and run it.
Steps -
1. Search for Icarus verilog , select the first link , then download the required file according to os and config of your pc .
2 .set the Environmental variables
3. Create your design file
4 . Use the below commands in your cmd
Compile it:
iverilog -o dsn counter_tb.v counter.v
Then run it:
vvp dsn
Then look at the test.vcd waveform:
gtkwave test.vcd &
Please do subscribe 👍
Namaste 🙏, everyone if you are facing any issues try downloading the latest version 👍😊
while trying to get the gtk waveform it is showing "GTK Analyser v3.3.48 (w)1999-2013 BSI " can u please let me know what to do
Thank you. Works perfectly
thank you for the tutorial, is there a way for you to execute the iverilog command outside the bin file? Or do I always have to save new projects into the bin folder? Thanks in advance
Thanks for this tutorial.
One doubt, is there anyway to get internal signals in gtkwave? I can only see the input/output ports in gtkwave
It was really helpful
and thanks alot🥰
'C:\iverilog\bin' is not recognized as an internal or external command,
operable program or batch file. error
object file test.v.txt command is not running, but simply test.v runs fine
Great content and good music also 👍
Namaste 🙏 Henry, thanks for the support, good luck and great health 👍😊
Hi, hear in the compilation and simulation command what is the meaning of "dsn"?
Thank You So much
In cmd I didn't get bin folder what can I do sir plz suggest me
Is there any software where we can directly write code and execute them without using cmd?
It's not working on my pc, whenever I am trying to run the test file. it's telling me "no top-level module, and no -s option",
I am getting same error
Save the test file in bin folder and rum command without writing .txt in enf
@@sahilraj690while trying to get the gtk waveform it is showing "GTK Analyser v3.3.48 (w)1999-2013 BSI " can u please let me know what to do
after i entered vvp dsn,its not displaying anything
I have installed iverilog and the first iverilog command is also working
but when I pass vvp test1
Its showing me "Unable to open input file"
What should I do??
Please check the name given in previous command
If I want to use iverilog, vvp and gtkwave cmd to compile and view waveform, should I separate "design.v" and "testbench.v" as two files ? Is it ok that I combine "design.v" and "testbench.v" in one .v file then go compile and follow-up process ? Thanks.
no u cant have them in same file
Love ❤
Thanks alot
When I am running the first cmd as iverilog.exe -o test test.v.txt then I'm getting error as syntax error and Missing close quote of string.
You can remove the ".txt" extension if your file is renamed to "test.v" only. Works for me.
how do I compile a file without having to put the file in the iverilog folder itself ? If my file is in another workspace how do I compile using iverilog ?
Same issue
@@sakshigandhewar4489 I resolved the issue, someone told me to download the latest version available rather than the one mentioned in this video, after I installed the latest version I can use the iverilog command anywhere
@@sakshigandhewar4489 ruclips.net/video/3Xm6fgKAO94/видео.html this is the video that helped me
if there are multiple modules interlinked to each other,then how do i run it on terminal
Give all file names in the commmand, or u can create a filelist and source it
in command prompt it is showing iverilog not recognised, i already added it to environmental variables and downloaded same version as you,kindly help me out
If u found how to install let me help also same I am also getting like that
How to solve it
is your background Palani by any chance??
hey can u please share the code ? is there any other way to excute this?
I love that you have riot games pile
Would you please provide the test codes of counter.v in the description.
This would help viewers to verify their system
Sure I will add
@@KarthikVippala please share code so that we can verify
The bin has different files.There is ntg called test.v 😭😭😭
"no top-level module, and no -s option" Error can be resolved by entering into command prompt "cd \iverilog\bin" then "iverilog test.v" then "vvp a.out" to get the output as"Hello, World".
hi same error, cant resolved can you please help me
@@anirbansarkar3104 For me, entering the command: "cd \iverilog\bin" followed by "vvp a.out" worked, got the output, hopefully it should work in your case too
can please provide to us that code
Thank you
Thanks for the support good luck,& great health 👍😊
@@KarthikVippala sir I want to enter into vlsi field
what I have to learn before doing mtech in VLSI design?
Now I am studying final year btech (ece)
We have verilog in this semester
@@KarthikVippala thanks for replying sir
Namaste BasavaRaju 🙏 , please ask all your questions , I will be interviewing a 30year vlsi expert to answer them for you.
i cant find test.v file in bin
Need to create it.
I am not getting that test.v file concept exact where we have to save that file as i am getting no such file directory error plzz reply it's urgent
I too
How did you solve it
any simulator for system verilog?
Namaskaram 🙏 Venkat , I will update you, if I find any free software.
Good luck & great health 👍😊
Am not able to find test.v in my system
I need how to do bro am not getting i need it urgently i have project submission
Namaste sardhar, we need create test.v manually,thanks for asking ,good luck & great health:)
@@KarthikVippala where we have to create
@@KarthikVippala when am going to create it was like new folder
Create a text doc
I am trying to install iverilog but during the cmd step my pc is replying i give up. syntax error again and again
Please try again it will work, Good luck & Great Health :)
facing the same issue!
Mine was showing the same issue but it was resolved after I saved the test.v file as All File and not as text docs
