## How it works

This tile design is rather simple - an 8:3 oncoder with the ability to invert the output if desired
This tile design is an active high 7:3 encoder, capable of inverting its output. Reference both the gate diagram and logic table below.

## How to test

Provide 8 signals, and then watch the 3 outputs
Provide 7 togglable signals to the input lines (0/3.3V) and connect the first 3 output lines to LEDs. When you toggle each line, you should see the LED change and show its binary representation.

## External hardware

On your signal outputs, hook up leds. This will give a visual indicator of the signals changing.
TTBoard and LED's should do just fine.
