Digital Design Colab Notebooks

This repository contains Google Colab pages for learning about and developing digital circuits. There are 3 types of notebooks.

• Tutorials
• Learning Exercises
• Design Labs

Explanations about each type of Notebook can be found on the wiki.

Getting Started

If you're new to this repository and are looking for a place to start, this notebook explains what you need to know about Google Colabs in order to follow along with the rest of the notebooks. We recommend opening it in a new tab.

Notebook List

The notebooks are organized into 5 notebook sets.

Dataflow System Verilog

Category	Notebook	Link	Description
Lesson	Boolean Algebra		Introduction to the boolean operators AND, OR, and NOT. Creating equations with these operators and performing analysis with truth tables.
Lesson	Logic Gates		Implementing boolean logic using logic gates. Introduction to XOR operator. Analyzing circuit diagrams composed of logic gates.
Lab	Logic Gates		This lab teaches how to use Gate Level logic (and, or, not) and how the Waveforms work. It doesn't require a board.
