//-----------------------------------------------------
// This is simple parity Program
// Design Name : parity

// Function : This program shows how a verilog
// primitive/module port connection are done
// Coder : Deepak

module parity (
a , // First input
b , // Second input
c , // Third Input
d , // Fourth Input
y // Parity output
);
// Input Declaration
input a ;
input b ;
input c ;
input d ;
// Ouput Declaration
output y ;
// port data types
wire a ;
wire b ;
wire c ;
wire d ;
wire y ;
// Internal variables
wire out_0 ;
wire out_1 ;
// Code starts Here
xor u0 (out_0,a,b);
xor u1 (out_1,c,d);
xor u2 (y,out_0,out_1);
endmodule // End Of Module parity
