A top-down hardware/software co-simulation method for embedded systems based upon a component logical bus architecture

We propose a top-down hardware/software co-simulation method for embedded systems and introduce a component logical bus architecture as an interface between software components and hardware components. Co-simulation using a component logical bus architecture is possible in the same environment from the stage at which the processor is not yet determined to the stage at which the processor is modeled in register transfer language. A model whose design is based on a component logical bus architecture is replaceable and reusable. By combining such replaceable models, it is possible to quickly realize seamless co-simulation. We further describe experimental results of our approach.
