精确的2.3分频代码
module fd23(clkin,clkout);input clkin;
output clkout;
reg clkout;
reg q2;
reg q3;
reg clk_10_times;
always@(posedge clkin)
begin
if(clk_10_times<3)
begin
if(q3<2)
begin
q3<=q3+1;
clkout<=0;
end
else
begin
q3<=0;
clkout<=1;
clk_10_times<=clk_10_times+1;
end
end
else if(clk_10_times<10)
begin
if(q2<1)
begin
q2<=q2+1;
clkout<=0;
end
else
begin
q2<=0;
clkout<=1;
clk_10_times<=clk_10_times+1;
if(clk_10_times==9)
clk_10_times<=0;
end
end
end
endmodule 用dds方式不能做吗？用不着这么扣呀加的 DDS怎么调用啊，QUARTUS可以吗， 回复 3# zhouliang
可以，找相应的IP核 好啊.....................
