Techniques of data transmission and information access for GNSS SoC verification platform

Verification for GNSS SoC depends on testing of huge amounts of immediate frequency(IF) data and statistical analysis of output information.Thus mass-data transmission and processing is one of the most significant difficulties.This paper focuses on techniques of simulation synchronization,IF data real-time transmission and debugging information management,then presents a scheme based on network protocols and relational database for information management.Through this platform the progress of GNSS SoC is under control.The data replay mechanism and information analysis are also implemented.The modules in this platform communicate with each other using TCP or UDP protocols.Low coupling among modules results in the ability to expand to the distributed architecture over network,adapting to the evolution of the navigation chip in the future.
