1、代码

module Gate(S_in1,S_in2,Out_and,Out_nand,Out_or,Out_nor,Out_xnor,Out_xor,Out_buf,Out_not);

input S_in1;
input S_in2;
output Out_and,Out_nand,Out_or,Out_nor,Out_xnor,Out_xor,Out_buf,Out_not;

and(Out_and,S_in1,S_in2); //与门
nand(Out_nand,S_in1,S_in2); //与非门
or(Out_or,S_in1,S_in2);//或门
nor(Out_nor,S_in1,S_in2);//或非门
xnor(Out_xnor,S_in1,S_in2);//同或
xor(Out_xor,S_in1,S_in2);//异或门
buf(Out_buf,S_in1);//缓冲器
not(Out_not,S_in1);//非门
//nand na1 3inp(Out_nand,S_in1,S_in2,S_in3)//三个输入

endmodule 

2、testbench

wire Out_nor;
wire Out_xnor;
wire Out_xor;
wire Out_buf;
wire Out_not;
