Digital Logic and Digital Design

What the page covers

The resources follow digital design from first principles to hardware. Early topics are binary numbers, truth tables and logic gates. Later ones reach CMOS circuits, timing, programmable logic and chip design flows. Most of the material is university level, with a smaller share for school students.

Where to start

Begin with the mind map Boolean Algebra & Logic Gates. It sets out NOT, AND and OR, then the commutative, associative and distributive laws, De Morgan and absorption. Next, the mind map Digital Systems explains why binary systems use only two values, 0 and 1, instead of the continuous values of analogue signals.

Then test the basics with the quiz PLC - Chapter 3: Number Systems and Codes, which asks about bases and binary conversion. The flashcard deck NAND Equivalence is a handy drill for building Not, And, Or, Nor and Xor from one gate type.

Moving into circuits and design

• The quizzes CMOS Logic Gate and CMOS Inverter Circuit cover pull-down and pull-up networks and noise margins.
• The mind maps on synchronous sequential logic, registers and counters, and memory and programmable logic cover the storage side.
• The Vhdl source file mind map follows a design from text file to synthesis on a target chip.
• The CAD Notes flashcards ask about top-down design, synthesis and the design cycle.

Using quizzes and maps together

Read a mind map first to see how the ideas connect. Then take a quiz on the same topic and note what you missed. Go back to the map for those branches, and use flashcards for the terms that keep slipping. Repeat until the quiz feels easy.
