描述

1. verilog实现基本门电路

verilog实现反相器，2输入与门、2输入或门、2输入与非门、2输入或非门、2输入异或门、2输入同或门；

撰写仿真程序，对实现进行仿真测试；

将仿真后的verilog代码进行综合与实现，并下载到basys3上验证；

2. verilog实现2选1MUX

撰写仿真程序，对其进行测试；

将仿真后的verilog代码进行综合与实现，并下载到basys3上验证；

input ［15:0］ sw，

output ［13:0］ led

）;

assign led［0］ = sw［0］ & sw［1］;

assign led［2］ = sw［2］ | sw［3］;

assign led［4］ = ~（sw［4］ & sw［5］）;

assign led［6］ = ~（sw［6］ | sw［7］）;

assign led［8］ = （sw［8］ & （~sw［9］）） | （~sw［8］ & sw［9］）;

assign led［10］ = ~（（sw［10］ & （~sw［11］）） | （~sw［10］ & sw［11］））;

assign led［12］ = ~sw［12］;

assign led［13］ = ~sw［13］ & sw［14］ | sw［13］ & sw［15］;

endmodule

4.测试模块

reg［15:0］ w;

wire［13:0］ l;

fpga001 f（w， l）;

initial

begin

w = 16‘b0;

#10 w = 16’b0010010101010101;

#10 w = 16‘b0101101010101010;

#10 w = 16’b0110010101010101;

#10 w = 16‘b1001101010101010;

#10 w = 16’b1010010101010101;

#10 w = 16‘b1111101010101010;

## This file is a general .xdc for the Basys3 rev B board

## To use it in a project：

## - uncomment the lines corresponding to used pins

## - rename the used ports （in each line， after get_ports） according to the top level signal names in the project

## Clock signal
