check the value 12321 is pallindrome or not by using constraint

module test();

class packet;

rand bit [7:0\] a;

constraint a{a inside {[0:4]};}

constraint a2 { foreach(a[i])

 { a[i]==a[(n-1)-i];}}

endclass

packet p1=new();

assert(p1.ramdomize());

$display("the value is =%p", p1.a);

endmodule
