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
This example shows the 3 approaches we can use to describe the hardware
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
