This tutorial paper describes different approaches to modeling and simulation of mixed-technology microsystems that consist of electrical circuits connected to subsystems described by partial differential equations (PDEs), which is a typical situation in many modern integrated circuits and systems. We target this paper towards the audience use of VHDL-AMS (a hardware description language suitable for modeling and simulation of such systems). We describe existing approaches to modeling such systems and present three examples accompanied by their VHDLAMS implementations and simulation results. r 2006 Elsevier B.V. All rights reserved.
