Modeling communication and circuit´s behavior

This session addresses difficult challenges in analog and mixed-signal modeling and simulation. The first paper proposes a model to describe the nonlinear behavior of a memresistor as a hybrid system and presents its implementation in VHDL-AMS. The second paper gives an overview of AMS circuit event-driven (real number) modeling, proposes a higher level of abstraction for this kind of modeling and describes experiences of implementing the proposed technique in various HDLs. The final paper addresses the high-speed communication between digital systems, which exhibits analog behaviour. Analog models are needed to evaluate correctly the impact of communication links on signal integrity. The paper discusses how this can be done at a high level of abstraction in SystemC-AMS.
