Is ther any method to generate and drive 1bit serial complex input stimulus?

I want to generate package using reference model and that package I want to drive in DUT though driver.
how can I do this?
how can I apply row input in that reference model using sequance ?
why I want to do this becouse my DUT want serial complex input so complex input I want to generate in reference model.
is ther any method to generate and drive 1bit serial complex input stimulus ?

In reply to Vrajesh_Rojivadiya:

You do not need a reference model to generate your data.
What you need is a seq_item class which has all parts of your data frame inside. The you generate a seq_item and this will be serialized in the driver.
