Designing And Implementation On Device Verification System For Independent Verification Package

With the information technology industry growing rapidly, data which is exchanged on the network is a massive amount of growth. Speed and quality of massive data exchange are guaranteed by high quality distributed switch, so it has relatively high demand for hardware and software of distributed switch, and the integrity of the hardware function and performance can be tested and verified by software of distributed switch.This paper bases on Independent Verification Package which is developed by driven development unit of Huawei Technologies Co., Ltd, describing the main design and implementation of the Independent Verification Package. In order to improve development efficiency, our company changes the method of hardware verification, using Independent Verification Package instead of product software. Independent Verification Package is more simplified, shorter development cycles and more efficient over product software. The main work is as follows:(1) The paper analyzes some common malfunctions of the distributed switch, and compares differences and similarities of the switch hardware verification in the traditional way and the new way of independent verification. And it disscuss the hardware architecture of distributed Ethernet switch, and code managing in development process, and working principle of communication between the boards during hardware verification.(2) Each module of the device verification system is designed and implemented, including device management initialization module, interface board management modules, fans management and power detection module module.(3) Some command lines are designed and achieved in the device verification system, including command line of device information query, command line of board reset and poweron and poweroff, command line of system time setting and query, command line of fan speed setting and query, command line of power query, command line of panel light control, command line of voltage signals query and command line CanBus status query.The device verification system designed by this paper has verified some kinds of card type, and achieved good results verification, meeting verification needs of hardware to prove the effectiveness of this work.
