SystemC-A modelling of mixed-technology systems with distributed behaviour

This paper presents an approach to modelling distributed systems described by Partial Differential Equa tions(PDEs) in SystemC-A. Such modeling approach is quite important because of the modeling difficulties for the mixed physical domain systems where complex digital and analogue electronics interfaces with vital distributed physical effects. As current SystemC-A does not support PDEs modeling, the proposed approach is based on discretization of PDEs to a set of Ordinary Differential and Algebraic Equations(ODAEs) which can be solved. Future work will extend the SystemC-A syntax to provide full PDE support. Distributed lossy microstrip and cantilever beam are used to validate the method and are described in the case studies.
