Fault modeling is an important step towards both understanding and validating the implemented system. The focus of the paper is to present a unified system fault modelling framework, including input related faults model based on system theory. The complex embedded system (CES) is modelled using sequence of communicating FSM (SCFSM) and the system faults are represented by two components of system fault vector -system behaviour fault vector and system communication fault vector. These two system fault vector components are related and are components of the "change parameter vector Θ", a general system level fault model based on Dynamic system theory. Input related faults are defined and their contribution is discussed. Faults propagation in mixed hardware software communication architecture is discussed, with the help of protocol example.
