导航SoC验证平台数据传输与信息存取技术

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

导航SoC的验证依赖于大批量中频数据的测试以及输出信息的统计分析,海量数据的高效传输和处理成为难点之一。文中研究导航SoC验证平台的运行同步、中频数据实时传输以及调试信息存取技术,提出了基于网络协议的平台框架,采用关系型数据库对信息进行组织和管理。通过该平台,能够控制导航SoC的运行,实现数据回放和调试信息分析。平台模块之间采用TCP/UDP协议进行通信,可以拓展到分布式的架构,以适应将来导航芯片的设计验证需求。

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.
