VHDL-AMS based modeling and simulation of mixed-technology microsystems: a tutorial

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 VHDL-AMS implementations and simulation results.
