Usb复合设备实现Usb完全覆盖测试的探讨

Discusssing of Usb Composite Devices to Achieve Usb Complete Coverage of the Test

Usb设备控制芯片或者控制器硬件模块开发的完成意味着测试的开始,通过对Usb测试流程的分析,提出了采用Usb多接口复合设备对Usb设备功能进行完全覆盖测试的方案,简化了测试的结构和流程,提高了Usb测试的效率和可实施性。

Accomplishment of Usb device control chip or controller hardware module's design means, the start of Usb test. The thesis analize flow of Usb test and gives a method of fully-covering test.This method makes use of Usb composite device with multiple interfaces, which simplifies the test codes' architecture and test flow, meanwhile enhancing efficiency and practicability of Usb test.
