Trade-off evaluation in embedded system design via co-simulation

Current design methodologies for embedded systems often force the designer to evaluate early in the design process architectural choices that will heavily impact the cost and performance of the final product. Examples of these choices are hardware/software partitioning, choice of the micro-controller, and choice of a run-time scheduling method. This paper describes how to help the designer in this task, by providing a flexible co-simulation environment in which these alternatives can be interactively evaluated.
