Mixed Signal Modeling

Abstract

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 ...
