With the increasingly high level of system integration it is becoming necessary to model not only electronic behavior of systems, but also interfaces to “real world” applications and the detailed physical behavior of elements of the system in question. The emergence of standard languages such as VHDL-AMS, Verilog-AMS, and Verilog-A has made it possible to now describe a variety of physical systems using a single design approach and simulate a complete system. Application areas where this is becoming increasingly important include mixed-signal electronics, electromagnetic interfaces, integrated thermal modeling, electromechanical and mechanical systems (including MEMS), fluidics (including hydraulics and microfluidics), power electronics with digital control, and sensors of various kinds. This is becoming increasingly relevant for systems using digital electronics such as microprocessors and even more so with FPGAs, as they offer the ability to manage multiple interfaces in parallel.
In this chapter, we will show how the behavioral modeling of multiple energy domains is achieved using mixed-signal modeling languages such as VHDL-AMS or Verilog-AMS, demonstrating with the use of examples how the interactions between domains takes place, and providing an insight into design techniques for a variety of these disciplines. The basic framework is described, showing how standard packages can define a coherent basis for a wide range of models, and specific examples are used to illustrate the practical details of such an approach. Examples such as integrated simulation of power electronics systems including electrical, magnetic and thermal effects, mixed-domain electronics, and mechanical systems are presented to demonstrate the key concepts involved in multiple energy domain behavioral modeling.
