🔬 ICE 2: Microblaze Custom Hardware

📌 Objectives

• Students should know how to integrate custom hardware with the Microblaze architecture

📜 Synopsis

In this ICE, you will add a counter with LEDs to the Microblaze hardware design then use a C program to interact with the counter through the serial terminal.

🧮 Procedure

• Download ice2.zip

• Part 1: Create Custom IP

• Part 2: Modify Custom IP

• Part 3: Package IP and Generate Bitstream

• Part 4: Export Hardware, Create C Project, and Run the Program

• The previous version of this tutorial is here.
