P2P-Based Full Digital Co-simulation and Verification System Design

With the embedded system showing a trend of network development, and gradually formed a Cyber-physical systems. How to ensure the safety and reliability of the Cyber-physical systems is a hot research topic in the present study. Full-digital co-simulation technology is an important means of verify the safety and reliability of embedded system, Cooperative communication is one of the key models of full-digital co-simulation system. Its network structure may affect simulation results and performance of system directly. Peer-to-Peer (P2P) network, a networking pattern developed rapidly in recent years, boasts unique advantages in coordinated working, P2P computing, resource sharing, etc. The paper studies the architecture of P2P network, proposes a P2P-based full digital co-simulation and verification system, focuses on the issuance/subscription mechanism of software bus, recommended strategy for timing simulation and activity detection mechanism of simulation node in the system, and designs experiments for analyzing the real-time simulation of the system.
