P.68 Inertial Delay AND Event DE-SCHEDULING

程式碼
module top;
reg x_in1,x_in2,y;
wire y_out;
AOI_2_unit m1(x_in1,x_in2,y_out);
initial
begin
x_in1=0;
x_in2=0;

#2000 $finish;
end
always
#50 x_in1=~x_in1;
always
#50 x_in2=~x_in2;
always
#50 y=~y;
endmodule

module AOI_2_unit(x_in1,x_in2,y_out);
input x_in1,x_in2;
output y_out;
wire y1;
and #3 (y1,x_in1,x_in2);
nor #2 (y_out,y1);
endmodule
