应用于导航芯片的SPI接口的设计与验证

Design and verification of SPI interface Used in Navigation Chip

本文采用自顶向下的Top-Down设计方法,详细描述了具有SPI协议的接口的设计与验证,包括接口的定义、模块划分、模块设计、接口验证,并给出了验证过程中收集的代码覆盖率和功能覆盖率,此款SPI接口已成功应用于导航芯片的模拟电路控制,具有实际的工程意义。

According to Top-Down design theory, the thesis described the design and verification of the SPI interface which has SPI protocol, including the defined of input and output signals, the divided of the modules, the design of the modules and the verification of the interface. It also presented the code coverage and functional coverage during verification. Presently, the SPI interface had been applied in the control of analog ciruit in the navigation chip, showing the validity in the enginerring application.
