Research on the Methods of SoC System Modeling and Simulation in YH-PBDE Environment

This paper puts forward a novel SoC system modeling and simulation method based on Constrained Taskflow Graph (CTG) as SoC system model, and implements a SoC system modeling and simulating tool in YH-PBDE environment which supports SoC SW/HW co-design. The tool can describe the SoC system behavior accurately and simulate the system at arithmetic level. It can support system re-use effectively. The example of Digital Soldier Audio/Video Decoder proves that this method ensures the accuracy of development and reduces the time of up-to-market.
