In this chapter, we will discuss concepts and techniques for modeling of systems at various levels of abstraction. We first present Models of Computation (MoCs) and design languages, which together provide the foundation for defining system behavior and models throughout the design flow. Based on these general principles, we then describe details of computation and communication modeling in the system components. The basic system component for computation is a processor with functionality that can be separated into application, operating system, hardware abstraction and hardware layers. Communication functionality can be modeled as stacks of network and protocol layers that are inserted into processors and CEs to realize drivers and interface hardware. In the end, we will show how these concepts and layers are combined into system models for application, system, and implementation designers in the form of a Specification Model (SM), a Transaction-Level Model (TLM) and a Cycle-Accurate Model (CAM), respectively
