Coupled device, circuit and interconnect simulation

摘要

In this paper, we discuss several aspects that are related to coupling device, circuit and interconnect simulation software. Straightforward co-simulation is too time-consuming, and hence reduced order modelling must be used in order to summarize the behaviour of individual simulations into compact models. From a theoretical point of view, the problem is complicated by the fact that equations of different type are being coupled. Mathematical techniques are indispensable for guaranteeing acceptable simulation times. The European project CODESTAR aims at providing a framework in which the aforementioned coupled simulations can be performed. The examples given in this paper have been taken from that project.
