This paper introduces a development and validation platform that combines hardware modeling and communication system simulation. This platform enables the use of a single platform for multiple purposes throughout a communication system design, including system simulation, software development and hardware modeling. Besides providing cycle accuracy hardware model, the platform is integrated with a multi-device simulation environment. Based on the platform, designers could complete protocol analysis and system simulation in a single stage. The platform is useful for the designs of communication components whose behaviors are highly coupled with transmission medium and other parallel components. In this paper, we will present the basic components and their design strategies.
