占空比50%的奇数分频
题目描述
设计一个同时输出7分频的时钟分频器，占空比要求为50%
注意rst为低电平复位。
信号示意图：
`timescale 1ns/1nsmodule odo_div_or(input wire rst ,input wire clk_in,output wire clk_out7);//*************code***********//reg[3:0]count_1; reg[3:0]count_2; reg[1:0] data;
always @(posedge clk_in or negedge rst)if (!rst)begincount_1 <= 0;count_2 <= 0;data <= 0;end
elsecount_1 <= count_1 + 1;always @(negedge clk_in or negedge rst)if (!rst)begincount_1 <= 0;count_2 <= 0;data <= 0;end
