How to use Wait On and Wait Until in VHDL
In the previous tutorial we learned the main differences between signals and variables. We learned that signals have a broader scope than variables, which are only accessible within one process. So how can we use signals for communication between several processes? We have already learned to use wait; to wait infinitely, and wait for to…
NOR logic gates interactive demo
Did you know that you can construct any other digital logic gate using only NOR gates? You can also do it with NAND logic. That’s why we say that these two are universal gates. This article shows one way to implement every logic gate using NOR logic, and the schematics are interactive, like a logic…
How to use a For loop in VHDL
In the previous tutorial we learned to create an infinite loop by using the loop statement. We also learned how the break out of a loop by using the exit statement. But what if we want the loop to iterate a certain number of times? The For-Loop is the easiest way to accomplish this. The…
Logic gates interactive demo
The basic logic gates NOT, AND, NAND, OR, NOR, XOR, and XNOR are fundamental building blocks in digital circuits corresponding to Boolean operators.
Play with the switches to see how the outputs change! 😀
NAND logic gates interactive demo
We can construct any other digital logic gate using only NAND gates as building blocks. This is why NAND is known as a universal gate. NAND logic is widely used as the foundation for designing digital circuits in modern integrated chips. Actually, NOR is also a universal gate, but NAND logic is more prevalent than…
How to delay time in VHDL: Wait For
In the previous tutorial we learned that a process can be thought of as a program thread. We also learned that a wait; statement causes the program to pause indefinitely. But is there a way to make a program wait for any other time value than forever? If we remove the wait; altogether and try…
Dear Jonas
Thanks for the content, thumbs up. please keep up the good work!
Best Regards
Thanks! That’s good to hear.
You are doing a very nice job. Top quality!
Thanks! I really appreciate your comment.
Hello Jonas
You really did save me by these great videos and materials.
These tutorials are the best thing on the internet.
Thank you for creating them.
Thanks! That’s encouraging to hear. I will do my best to keep up the quality of my blog posts.
Thank you so much man you are awesome! i learnt vhdl in university but i forgot after all years. i started again working. You help me too much! i will continue to course after this beginner course. i am planning the begin beginner fast track ! please dont stop the teaching us . thank you so much! greetings from turkey 🙂
Hello, Utku. Thank you for the nice comment! I’m glad you found my blog to be helpful. I will keep the free and premium content coming your way.
Thank you for providing such great content on a subject that imo can be tricky to really understand. But you make it easy for everyone!
That’s great to hear! I will keep on creating tutorials and articles for you. ?
Dear Jonas,
I’m an electronic engineer from Morocco, currently studying for a masters degree in microelectronics and sensors in France.
You helped me a lot to remember some of the vhdl basics and get more further into it.
I worked on an academic project using basys3 and vivado for a vga controller.
Thank you very much for this great content, keep up the good work.
I’m glad you like the quiz. It’s a good way to refresh your knowledge. 🙂
Excellent learning tool
Thanks! By the way, I also use quizzes in the VHDLwhiz membership.
Great tutorials! Short and sweet!
I’ll be sure to go onto the FPGA and VHDL Fast-Track after completing the basic tutorials..
Thanks, Dale! Also, check out the VHDLwhiz Membership, which gives you multiple courses, resource items, and coding challenges and supports your success in FPGA design.
Nice quiz, only problem is sharing your score on facebook is not working.
Thanks for the feedback. I’ve created a task on this. I’ll see if I can fix it when I have the time.
