Requirements


❗ VHDL and Digital Electronics basics needed.
❗ No Flash knowledge needed.
❗ No SPI Protocol knowledge needed.

Description


Have you ever wondered how your FPGA remembers its configuration after you unplug it?
The answer is SPI flash memory — and in this course, you will build a complete driver for it from the ground up, in VHDL, on real hardware.
This is a hands-on, board-level course. By the end, you will have designed a working system that lets you type a message into a terminal, store it permanently in flash memory, power the board off, power it back on — and watch your message reappear. No microcontroller. No operating system. Pure hardware logic running on a Xilinx Spartan-6 FPGA.
What you will build
The course is structured around five practical deliverables
✨ Areusable SPI master — a VHDL state machine that generates SCLK, drives MOSI, and captures MISO at any clock speed
✨ Aflash driver — a command-level FSM that implements READ, PAGE PROGRAM, SECTOR ERASE, and WIP polling on top of the SPI master
✨ AUART interface — a 19200-baud 8N1 transmitter and receiver so you can interact with the board from any terminal
✨ Acomplete testbench
✨ TheMessage Board capstone project — a persistent EEPROM-style storage system that ties all four components together into a single top-level design

What You Will Learn


✨ How the SPI protocol works
✨ How flash memory stores, erases, and protects data at the cell level
✨ How to design layered hardware — a transport layer, a command layer, and an application layer that are each independently testable

Who this course is for


⭐ Engineering students
⭐ Anyone interested in hardware design and system integration
