Abstract modelling of switching elements for optical networks-on-chip with technology platform awareness

Abstract

This paper reports the lessons learned in the abstraction process of the behaviour of switching elements for optical networks-on-chip, resulting in technology-annotated abstract models for the SystemC modelling and simulation environment. The paper points out the key physical effects that a designer should be aware of to properly assess effectiveness and feasibility of photonic switching fabrics. Moreover, the sources of inaccuracy are analysed when composing models of basic optical devices into higher order switching structures. Finally, a technique for modelling optical links into the SystemC framework is presented, by leveraging the pre-existing channel constructs. The findings of this paper capitalize on an extensive validation effort of abstract simulation models with FDTD simulations.
