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 Port Map instantiation in VHDL
A module is a self-contained unit of VHDL code. Modules communicate with the outside world through the entity. Port map is the part of the module instantiation where you declare which local signals the module’s inputs and outputs shall be connected to. In previous tutorials in this series we have been writing all our code…

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 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…

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 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…

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.
