Abstract: System-level design methodology is adopted due to the complex VLSI design. With the case study of a multi-port Ethernet switch controller, the system-level model is developed. By simulating this model, the feasibility analysis and performance evaluation are performed. As a result, the subsequent design flow is accomplished, and the design specification is correctly implemented on the basis of the system-level design paradigm.
