VHDL-AMS modeling method of digital integrated circuit based on IBIS

摘要

This paper focuses on digital integrated circuit modeling method to characterize its function and transmission properties. The proposed method constructs the behavioral model of a digital integrated circuit, which is composed of the IO buffer section and functional section. The IO buffer section is described by IBIS, and the functional section is depicted by HDL. The two sections of the model are developed by using VHDL-AMS language. The model developed by this method is universal for any commercial digital device and has higher simulation speed than SPICE. At the end of this paper, the proposed method is verified through comparison with SPICE simulation.
