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]count;
always @(posedge clk)
begin
    if(rst)
    begin
        pwm_out<=1'b0;
        count<=4'b0;
    end else
    begin 
        count<= count+1;
        if(count<duty)
        begin
            pwm_out<=1'b1;
        end
        else
        pwm_out<=1'b0;

    end
end
