1.实验目的：
使用verilog HDL硬件描述语言乒乓球游戏电路设计

2.实验内容：
在这里插入图片描述

3.实验原理：按照视书上的内容，书写和运行代码，完成仿真操作
实验代码：
（1）

module pingp(clk, reset, push1, push0, led, decode1, decode2, decode3, decode4, clk_out);
	input clk, reset;
	input push1, push0;
	output [6:0] led, decode1, decode2, decode3, decode4;
	output clk_out;
	
	fenpin hz(clk, reset, clk_out);
	ctl ctll(.clk(clk),.reset(reset),.push1(push1),.push0(push0),.led(led),
	.decode1(decode1),.decode2(decode2),.decode3(decode3),.decode4(decode4));
	
endmodule

	always@(posedge clk)
	begin

			begin
				led<=7'b0000000;
				M<=4'b0000;
				N<=4'b0000;
			end
		else

							end
					end
					s1:								//甲发球或甲接球后，球的移动
					begin

							end
					end
					s2:if(push1)			//乙接球
							begin
