Introduction

This page is meant to help understand how to approach the language. There are three levels of abstraction.

Way to describe Hardware

  • Gate Level
  • Dataflow Level
  • Behavioral Level

Types of Logic

  • Combinational Logic
  • Sequential Logic

Combinational Logic

This is where the outputs are a simple function of the inputs. (Sounds like pure functions

2 to 1 Multiplexer

Gate Level

This was quite useful as I have some knowledge of gates and boolean logic so it starts to make a bit of sense in verilog. Here is the truth table for the 2 to 1 multiplexer

To model this at the gate level we could do this

Sequential Logic

Sequential logic uses memory and state
