Introduction to VHDL programming


In this course on digital electronics and logic design with VHDL, students will learn the digital electronics concepts from scratch and also learn VHDL programming concepts to design digital circuits by writing the programs in textual form mapped into digital with this front end language of VHDL. In any programming language, we need a strong foundation of the fundamentals particularly the usage of syntax. Once if you are strong enough in usage the syntax properly, then students will feel comfortable and have some ease to write programs easily. Nowadays everywhere is full of digital circuits embedded in the systems without digital we cannot imagine our life. If you are really interested in digital electronics and digital circuits behaviours and how to design the digital circuits this course is absolutely for you. The course is designed in the below manner.

Course structure:

Section1: In this section, you may learn about what is a system and the digital systems as well as the basic understanding of number systems, after that the conversions of number systems will be clearly discussed like decimal to any radix and any radix to decimal. Next data representations like signed magnitude and signed 1’s, signed 2’s complement techniques are discussed here. Binary arithmetic like addition, subtraction, multiplication, and division along with different binary codes are clearly explained.

Section 2: Boolean theorems and their functions, as well as the sum of product, forms (SOP), and product of sums (POS)  forms and also you may learn the conversion of SOP  into SSOP /CSOP as well as POS into SPOS/CPOS forms, etc., Of course, duals of a boolean function and de morgan’s laws also explained. Next explained the basic logic gates and their truth tables and. Equivalence of basic gates or alternative gates for basic gates and different logic circuit implements with gates discussed.Minimization of boolean logic
expressions,   Grey to Binary Vice versa Conversions.  Overview of Karnaugh map variable k-map   2 variable k-map    3 variable k-map 4 variable k-map discussed.

Section 3 Deals with the implementation of combinational logic circuits like the design analysis procedure for design the combinational logic circuit half adder, full adder, half subtractor, full subtractor, and parallel binary adder .Using binary adders implementation of 1’sc and 2’s complement combinational circuits .designed.circuits. Adder-subtractor with parallel binary adders by using control input explained. The next is Decoder introduction is 2 to 4 decoder,  3 to 8 decoder, and  3 to 8 decoder combinational logic circuit implementation.

Section4: Deals with VHDL programming basics. The first part is dealing with the inside of the main code. while the second one deals might be the library. In this course code structure, different data types, operators, concurrent and sequential codes also covered fundamentally associated with the VHDL language. 

This course also focuses on teaching students about the full details of digital circuits and how the syntax of VHDL is interpreted and how it can be used to design digital circuits and the main distinguishing feature is that it teaches in detail all indispensable and synthesis in a concise format of features in VHDL.

This course is well suited for:

Who wants to learn digital electronics and circuits concepts.

Engineering graduates( students in graduation level) to get a bachelors degree

Helpful to do some projects with VHDL hobbyists.

Happy learning
