i don't know about cadence,but i think the problem is you have not specified the common mode voltage(you have to put separate common mode voltage source).
Thanks,

Thanks for your reply. Actually I had already specified common node voltage.
I also tried seperating them but it did not work. I think it is not a problem whether to seperate them or not. As I saw they are connected together in the jacob text book in spice.
