一个比较简单的秒表计数器。

`timescale 1ns/1ns

module count_module(
	input clk,
	input rst_n,

    output reg [5:0]second,
    output reg [5:0]minute
	);
	
  	// 秒
    always@(posedge clk or negedge rst_n) begin
        if(~rst_n)
            second <= 0;
        else
            second <= minute==60? 0:
                      second==60? 1: 
                      second+1;
    end
  
  	// 分
    always@(posedge clk or negedge rst_n) begin
        if(~rst_n)
            minute <= 0;
        else
