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 use conditional statements in VHDL: If-Then-Elsif-Else
In the previous tutorial we used a conditional expression with the Wait Until statement. The expression ensured that the process was only triggered when the two counter signals where equal. But what if we wanted the program in a process to take different actions based on different inputs? The If-Then-Elsif-Else statements can be used to…

Dual 7-segment display FPGA controller
In this article, I will present a VHDL module that can display a two-digit number on the Pmod SSD: Seven-segment Display from Digilent. The dual 7-segment display is compatible with the Pmod interface, meaning that you can use it without any soldering. It fits into the Pmod connector, which is standard on many FPGA development boards.

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…

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 a signal is different from a variable in VHDL
In the previous tutorial we learned how to declare a variable in a process. Variables are good for creating algorithms within a process, but they are not accessible to the outside world. If a scope of a variable is only within a single process, how can it interact with any other logic? The solution for…

How to stop simulation in a VHDL testbench
How do you stop the VHDL simulator when the simulation is complete? There are several ways to do that. In this article, we will examine the most common ways to end a successful testbench run. The VHDL code presented here is universal, and it should work in any capable VHDL simulator. For the methods involving…
Dear Jonas
Thanks for the content, thumbs up. please keep up the good work!

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.
