ECE 272

Digital Logic Laboratory

This lab enables opportunities that facilitate learning both combinational and simple sequential designs. These designs are implemented using a Lattice FPGA through schematic capture and Verilog. Some examples of projects are adders, 4 digit seven segment display controllers, SPI communicators, and even an open ended final design project.

The following lab material requires Adobe Acrobot Reader to view.

Preface

Section 1: Basic Combinational Logic and the MachXO2

This section covers the basics of using the Lattice Diamond software to program an FPGA, and connecting the Lattice Breakout Kit to the button board.

Section 2: Adders on an FPGA

Learn about number systems and adders.

Section 3: Combinational Logic (Seven Segment Driver)

Pre-lab

Design a 7- segment display decoder.

Section 4: Driving multi-digit LED displays

Pre-lab

Use a state machine to cycle through digits fast enough to blur separate images together into a single number.

Section 5: Voltmeter

Pre-lab

Design a system that will measure an analog voltage and display it using a multi-digit 7 segment display.
ADC Module

Section 6: Final Design Project

Pre-lab

Design something creative.
