sir 

actually this is the code which i have written . and i want to ask can i connect   8 bit b with 6 bit a as following i have wrriten. 

module  sonu (a);

  input [6:0] a ;

endmodule

module sin;

  reg [8:0] b;

  

  sonu www(.a(b[8:0]));

  

endmodule

In this basically u did the wrong instantiation b will be inside and a will outside with "." operator. And you cannot connect a 8 bit bus to two sources by dividing bits (i.e 4 bit to one and remainning to other) this is wrong method. because u cannot drive a bus with two different resources.
