Assignment 1: Designing a 4-Bit Binary Counter


In this assignment, students are tasked with designing a 4-bit binary counter using Verilog. The goal is to create a synchronous counter with the ability to count up or down based on an external control signal. This task not only tests the student's understanding of Verilog syntax but also challenges their logical reasoning and ability to implement complex digital circuits.


// Verilog Code for 4-Bit Binary Counter
module BinaryCounter (
    input wire clk,         // Clock input
    input wire rst,         // Reset input
    input wire up_down,     // Up/Down control input
    output reg [3:0] count   // 4-bit binary counter output
);

always @(posedge clk or posedge rst) begin
    if (rst)
        count <= 4'b0000;   // Reset the counter to 0
    else if (up_down)
        count <= count + 1;  // Increment counter for 'up' direction
    else
        count <= count - 1;  // Decrement counter for 'down' direction
end

endmodule


Solution Overview:


  • The always block is sensitive to the positive edge of the clock (posedge clk) and the positive edge of the reset signal (posedge rst).

  • The counter is reset to 0 when the reset signal is active (rst).

  • Depending on the value of the control signal (up_down), the counter either increments or decrements.


Assignment 2: Implementing a Finite State Machine (FSM) for a Traffic Light Controller


This assignment focuses on designing a Verilog module for a traffic light controller using a finite state machine (FSM). The FSM should handle the transitions between different states, such as Green, Yellow, and Red lights, based on specific timing requirements. Students need to demonstrate their understanding of state machines, sequential logic, and Verilog coding principles.


// Verilog Code for Traffic Light Controller FSM
module TrafficLightController (
    input wire clk,         // Clock input
    input wire rst,         // Reset input
    output reg [2:0] state   // Output representing current state (Green, Yellow, Red)
);

typedef enum logic [2:0] {
    Green = 3'b001,
    Yellow = 3'b010,
    Red = 3'b100
} state_t;

reg [2:0] next_state;

always_ff @(posedge clk or posedge rst) begin
    if (rst)
        state <= Green;   // Reset to initial state (Green)
    else
        state <= next_state;  // Update state based on next_state value
end

always_ff @(posedge clk or posedge rst) begin
    if (rst)
        next_state <= Green;  // Reset to initial state (Green)
    else begin
        case (state)
            Green: next_state <= Yellow;  // Transition from Green to Yellow
            Yellow: next_state <= Red;    // Transition from Yellow to Red
            Red: next_state <= Green;      // Transition from Red to Green
        endcase
    end
end

endmodule


Solution Overview:


  • The module defines an enumeration (state_t) for the different traffic light states.

  • Two always_ff blocks handle the state transitions and updates based on the clock signal (clk) and reset signal (rst).

  • The traffic light transitions through the states Green -> Yellow -> Red -> Green in a cyclic manner.
