Project Assignment Instructions Digital Design (Quartus II & ModelSim)

You are required to complete a full digital design project that includes design, implementation, simulation, report writing, and presentation. The project consists of two main sections: Dice Game and GCD Calculator. Make sure all work is accurate, complete, and professionally presented.

# Section 1: Electronic Dice Game Design

Design and implement an electronic dice game using VHDL based on the given rules.

## Steps to follow:

### 1. Understand the System

– Two counters simulate two dice (values from 1 to 6).

– The sum ranges from 2 to 12.

– Apply the game rules exactly as described.

—

### 2. Design the System Architecture

You must divide the system into:

– Data Path:

– Two counters (16)

– Adder (sum)

– Comparator

– Point Register

– Control Unit (FSM):

– Design an ASM (Algorithmic State Machine)

—

### 3. FSM States (Required)

Include at least the following states:

– IDLE

– ROLL

– CHECK_FIRST

– STORE_POINT

– CHECK_NEXT

– WIN

– LOSE

—

### 4. VHDL Implementation

– Write clean, modular VHDL code:

– Separate files for datapath and control unit

– Use meaningful signals and proper naming

– Add clear comments

—

### 5. Simulation (ModelSim)

– Create a testbench

– Verify:

– Dice rolling

– Sum calculation

– Win/Lose conditions

– Provide waveform screenshots

—

—

# Section 2: GCD Calculator Design

Design a digital circuit to compute the GCD of two N-bit numbers (e.g., 8-bit) using the Euclidean algorithm.

—

## Steps to follow:

### 1. Understand the Algorithm

Repeat:

– If A < B B = B – A

– Else A = A – B

Until A = B

—

### 2. Design the Architecture

– Registers: A, B

– Subtractor

– Comparator

– MUX

– Control Unit (FSM)

—

### 3. FSM States

– IDLE

– LOAD

– COMPARE

– SUBTRACT

– DONE

—

### 4. VHDL Implementation

– Modular design (datapath + control unit)

– Use clocked processes

– Ensure correct reset behavior

—

### 5. Simulation

– Apply different test cases

– Show:

– Input values

– Iterations

– Final GCD

– Done signal

—

—

# Quartus II Requirements
