30. PWM with 4-bit Resolution

How do you plan to solve it?

/*Write your code here*/

module pwm4_basic(
    input wire clk,
    input wire rst,
    input wire [3:0] duty,
    output reg pwm_out);

    reg [3:0] count;

    always @(posedge clk) begin
        if (rst) begin 
            pwm_out <= 1'b0;
            count <= 4'b0000;
        end

        if (count < duty) pwm_out <= 1'b1;
        else pwm_out <= 1'b0;

        count = count + 1'b1;

        
    end
