Simulation and Modelling Expertise of Complex Hybrid Systems
Fraunhofer Institute for Electronic Nano Systems
The development of simulation methods for complex micro and nano electronic systems takes place in close co-operation with the University of Paderborn (Fakultät Elektrotechnik, Informatik und Mathematik). The task spectrum covers all relevant aspects of the system design, starting from the chip over package and module up to the PCB.
One focus of the work lies on the characterization of complex electronic systems by modeling, simulation and measurement of parasitic electromagnetic effects. For this purpose the ASE uses most diverse commercial simulation tools (e.g. CST studio Suite, Agilent ADS) and an ambitious measuring instrument equipment that allows the examination of most different parasitic effects.
During the development and characterization of 3D structure technologies beside the electrical also the thermal and mechanical characteristics of new structure technologies can be examined by simulation just before a prototype draft is available.
Due to the growing complexity of the systems to be simulated, the expenditure of time and the costs involved are also increasing. Therefore efficient and accurate models are required in order to reduce the demand on time and computational resources. For this purpose, in the department ASE methods are analyzed, which are capable of approximating the transfer functions of linear systems in the time-domain as well as in the frequency-domain (e.g. vector fitting)
For the treatment of nonlinear systems, so called Radial Basisfunction-nets are used. By means of specific system identification algorithms (order estimation, parameter adaptation) it is possible to approximatively describe the behavior of complex nonlinear systems with this particular form of the well-known Neural Networks.
