fpga-oscilloscope's Introduction

FPGA-Oscilloscope

This repository contains all files related to the design and creation of my FPGA Oscilloscope. The oscilloscope is based on the Altera Cyclone III EP3C40 FPGA as part of my Caltech EE 052 class project.

Included documents:

- Documentation
    - Functional Specification
    - System Block Diagram
    - Planned Board Layout
    - Memory Map
    - Cyclone III Pinout
- Circuit
    - Schematic Diagram
    - Board Layout
- Code
    - Quartus FPGA Code
    - NIOS Program Code
