4. The method of claim 1 , wherein said determining, from the original model, the logic to be abstracted includes one or more of: determining a first register in the first netlist and a corresponding second register in the second list; determining a first next-state function of the first register; and determining a second next-state function of the second register.

The method of claim 4 , wherein: said determining, from the original model, the logic to be abstracted includes determining a first next-state function of the first register and determining a second next-state function of the second register; and said determining the condition for functional consistency includes determining that the first next-state function of the first register and the second next-state function of the second register are functionally equivalent when the first next-state function of the first register and the second next-state function of the second register receive a same input.
