Behavioural macromodels of digital IC receivers for analogue-mixed signal simulations

摘要

A behavioural multiport macromodel for the input buffers of digital integrated circuits is presented, including the bit detection and the effects of power-supply fluctuations. The model is given in terms of mathematical expressions, thus preserving proprietary information of designers, and offers comparable accuracy and improved efficiency compared with transistor-level models. It is also completely compatible with SPICE, VHDL-AMS and IBIS implementations.
