Multiphysics modelling and simulation in Berkeley MAPP

We introduce the newly-developed modules for multiphysics modelling and simulation in Berkeley Model and Algorithm Prototyping Platform (MAPP). Using them, developers can write compact models for not only electronic devices, but also those from optoelectronics, spintronics, microelectromechanical systems (MEMS), etc. They can also connect these device models into systems using multiphysics netlists and run various simulation algorithms on them. In this paper, we explain the key concepts and techniques behind these modules, and illustrate the usage of them through examples. Our plan is to make them available in open-source form as part of MAPP under the GNU Public License.
