Abstract: Decision diagram model is a utility to represent data dependence between signals in VLSI designs, and is widely used in VLSI design verification. This paper extends the existent DD model, presents and implements a method of extract DD model from HDL description. This method gets promising result when integrated in a RT-level automatic simulation vectors generation system.
