Learn VHDL and FPGA Development
This course supports both the Xilinx and Altera FPGA development boards.
VHDL and FPGA Development for Beginners and Intermediates is a course that is designed to teach students how to create and successfully simulate their VHDL design. We will also be implementing these designs on a Xilinx BASYS 3 or BASYS 2 FPGA development board so that the students can see their designs actually running. This course starts from beginning to end in teaching the user how to turn their digital logic design into VHDL designs that can be simulated in ModelSim or ISim and then implemented on an FPGA development board. This course also covers how to use Altera’s tools so students are not limited to Xilinx development boards.
This course contains over 20 lectures that will teach students the syntax and structure of VHDL. The student will be able to understand the syntax and use of specific VHDL keywords by taking this course. There are lectures included in each lab to give a background on the digital logic circuit the student will be implementing.
This course contains 7 labs that are designed so that the student will learn how to develop VHDL code. For each lab I will give the student a set of VHDL files that they will have to modify or change in order to get the project to simulate correctly in ModelSim and so they can implement the design on their FPGA board. These labs are design to help the students learn VHDL by actually coding it themselves.

This lecture introduces this course, I will introduce myself as well as explain what will be covered in this course. The course layout is explained in this course.
Introduction to VHDL and the different ways you can use VHDL. This will give you a better understanding of what VHDL is doing and how it differentiates from a software programming language.
VHDL Data Types
This lecture introduces the various data types used in the VHDL language. All of these data types are then explained more thoroughly in the later lectures.
This lecture talks about what variables, signals, and constants are and how they are used in the VHDL language.

This lecture takes students through an example VHDL design and discusses the various data types being used throughout the design.
This lecture introduces the VHDL Syntax section and explains everything that will be covered in this section.
If statements and case statements are commonly used in various programming languages. These statements are also used in VHDL and I will explain how in this lecture.
This lecture walks through and discusses how for loops and while loops are used in VHDL.
This lecture explains the differences between a for loop in VHDL verses a for loop in a software programming language such as c++.
This lecture discusses two different statements in VHDL, the when-else statement as well as the with-select-when statement.
In VHDL things happen concurrently by nature, however with the use of processes and variables we can make things happen sequentially. In this lecture I will discuss the difference between them.
This lecture walks through a VHDL design and discusses the layout and structure of the VHDL syntax.
This is a quiz that goes over the material covered in section 2 VHDL Language Basics
VHDL Coding Structure
