I’m from Norway, but I live in Bangkok, Thailand. Before I started VHDLwhiz, I worked as an FPGA engineer in the defense industry. I earned my master’s degree in informatics at the University of Oslo.

How to create a finite-state machine in VHDL
A finite-state machine (FSM) is a mechanism whose output is dependent not only on the current state of the input, but also on past input and output values. Whenever you need to create some sort of time-dependent algorithm in VHDL, or if you are faced with the problem of implementing a computer program in an…

How to check if a vector is all zeros or ones
I know that I have googled this at least a hundred times throughout my career as an FPGA engineer; how to check if all bits in a std_logic_vector signal are ‘0’ or ‘1’. Of course, you know a few ways to do it already, but you want to find the most elegant code that will…

How to create a concurrent statement in VHDL
A concurrent statement in VHDL is a signal assignment within the architecture, but outside of a normal process construct. The concurrent statement is also referred to as a concurrent assignment or concurrent process. When you create a concurrent statement, you are actually creating a process with certain, clearly defined characteristics. Concurrent statements are always equivalent…

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…

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! 😀

How to use a procedure in a process in VHDL
It is possible to drive external signals from a procedure. As long as the signal is within the scope of the procedure, it can be accessed for reading or writing, even if it isn’t listed in the parameter list. Procedures that are declared in the declarative region of the architecture, cannot drive any external signals….

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.
