ZYNQ7000(十二)学习使用VIO（virtual input output）以及进行试验

视频十二：学习使用VIO（virtual input output）以及进行试验

1.配置Vio

1. 第一步:generate block designed → add ip vio 完成三个设置；

学习数据手册：

0：12分；
下一步：增加角Ctrl+ t 加三个；
生成顶层文件
2.create HDL wrapper
选择第一个：

2.1进行修改：

`timescale 1 ps / 1 ps

module design_12_wrapper
(clk,
SW,
LED);
input clk;
input [7:0]SW;
output [7:0]LED;

design_12 design_12_i
(.clk(clk),
.probe_in0( SW ),
.probe_out0( LED ));
endmodule
2.2在constrs_1增加约束文件：
set_property PACKAGE_PIN Y9 [get_ports {clk}]
set_property IOSTANDARD LVCMOS33 [get_ports {clk}]

set_property PACKAGE_PIN T22 [get_ports {LED[0]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[0]}]

set_property PACKAGE_PIN T21 [get_ports {LED[1]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[1]}]
set_property PACKAGE_PIN U22 [get_ports {LED[2]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[2]}]
set_property PACKAGE_PIN U21 [get_ports {LED[3]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[3]}]
set_property PACKAGE_PIN V22 [get_ports {LED[4]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[4]}]
set_property PACKAGE_PIN W22 [get_ports {LED[5]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[5]}]
set_property PACKAGE_PIN U19 [get_ports {LED[6]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[6]}]
set_property PACKAGE_PIN U14 [get_ports {LED[7]}]
set_property IOSTANDARD LVCMOS33 [get_ports {LED[7]}]

set_property PACKAGE_PIN F22 [get_ports {SW[0]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[0]}]
set_property PACKAGE_PIN G22 [get_ports {SW[1]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[1]}]
set_property PACKAGE_PIN H22 [get_ports {SW[2]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[2]}]
set_property PACKAGE_PIN F21 [get_ports {SW[3]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[3]}]
set_property PACKAGE_PIN H19 [get_ports {SW[4]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[4]}]
set_property PACKAGE_PIN H18 [get_ports {SW[5]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[5]}]
set_property PACKAGE_PIN H17 [get_ports {SW[6]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[6]}]
set_property PACKAGE_PIN M15 [get_ports {SW[7]}]
set_property IOSTANDARD LVCMOS33 [get_ports {SW[7]}]

3.生成比特流文件；

下载之后：

（注：第一个为为控制led输入输出的；第二个为温度显示）

把输入输出添加进去就可以了

上面改变就可以实时控制led的亮灭；

温度显示：
