3. Course Description
Programmable Logic and FPGAs in particular are used in just about every digital electronics system
Getting started on your first FPGA design can be a daunting prospect however
New concepts, new tools, new languages, etc.
This course will provide a painless introduction and a hands on opportunity for you to do your first actual design, making it easy for you to get started on your first programmable logic design

4. Today’s Topics Goals and Objectives
What is Programmable Logic and what are FPGAs?
Key features
Lattice LCMXO2-1200ZE Quick Review
Quick Overview of the Development Flow, Evaluation Board, Example Design

5. Todays Goals and Objectives
Understand Programmable Logic and FPGAs
Understand the key tools and methodology used when designing FPGAs
Understand the specific device, board and tools we will use during the course

11. Development Flow Define the system
System Definition
Define the system
Program the Processor in “C” or Assembly
Libraries
Program the FPGA in HDL (VHDL or Verilog)
IP Blocks
Simulate, Program and Debug

12. Evaluation Board Use the board to test out design flow
Example designs are helpful in getting started
Enough hardware to try out your own design
Evaluation vs. Development- know what you want to do

13. Other Types of Boards Evaluation Board Development Board
Development Platform
Reference Design

14. Example Design Targeted to Pico Eval Board Block Diagram
Power Regulator
ADC Voltage Measure
Display on LCD
EFB SPI/I2C Slave
