30. PWM with 4-bit Resolution

How do you plan to solve it?

/*Write your code here*/
module pwm4_basic(input clk,rst, input [3:0] duty, output reg pwm_out);

reg [3:0] cnt;

always@(posedge clk)begin
    if(rst) begin
        cnt<=0;
        pwm_out<=0;
    end

    else begin
        cnt<=cnt+1;
        if (cnt<duty) pwm_out<=1;
        else pwm_out<=0;
    end



end
