利用verilog实现基本门电路
2018-07-09
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;
led[0] sw[0] sw[1]实现2输入与门

3.实现模块
module fpga001(
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);

## 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
