【摘要】：Intel HWV循环供电测试系统(HPCTS:HWV Power Cycling Test System)是本文作者在英特尔亚太研发有限公司PEG—HWV (Platform Engineering Group—Hardware Verification)部门任硬件实习生时独立担任的研发项目,旨在为Intel服务器主板提供一套完善的循环供电测试方案。与原有测试方案相比,该方案能大大提高循环供电测试的效率,缩短对服务器主板硬件进行测试、纠错的时间。HPCTS已得到本部门主管、Intel PEG—BIOS部门主管以及Intel PEG—BDE (Board Design Engineering)主管的认可及支持,目前已进入方案调整试用阶段。循环供电测试是服务器主板测试过程中最先开始、也是最为重要的一项测试,通过不同类型的循环供电测试能够反映主板硬件的健壮性、固件(如BMC、BIOS和外设控制器固件等)的稳定性以及与操作系统(Linux, Windows OS)的兼容性等方面。之前的循环供电测试方案局限于单个服务器主板的一种循环供电测试,一旦测试出现问题,则难以定位并解决问题,而笔者独立研发的HPCT由于支持多个主板的不同类型循环供电测试,可实现跨平台测试比对,跨类型测试比对,从而协助测试工程师更迅速地定位问题源头进而解决问题,节省了主板测试纠错的时间。本循环供电测试方案包括HPCT测试工具的硬件、固件设计,面向测试人员的上位机软件设计,符合Intel服务器循环供电测试标准的主板BIOS的修改及配合循环供电测试的主板自动检测软件批处理脚本的设计。需要了解或掌握的知识涵盖嵌入式硬件设计、嵌入式固件开发、微软Windows OS多线程编程、Intel服务器循环供电测试标准、Intel服务器硬件架构及服务器BIOS架构、BIOS开发以及Intel服务器硬件上电掉电时序等等。其中有相当一部分知识来自Intel内部资料——如服务器硬件架构,系统内存映射,BIOS C语言源代码等,由于NDA限制,无法公开。本文将侧重从设计思路和设计方法的角度阐述整个方案,从设计原理的角度说明该方案的创新点,从实际验证的结果证明该方案的可行性和发展空间。
[Abstract]:Intel HWV cyclic Power supply Test system (HPCTS:HWV Power Cycling Test System) is an independent research and development project when the author worked as a hardware intern in Intel Asia Pacific R & D Co., Ltd. PEG-HWV (Platform Engineering Group-Hardware Verification. The purpose of this paper is to provide a set of perfect cyclic power supply test scheme for Intel server motherboard. Compared with the original test scheme, this scheme can greatly improve the efficiency of cyclic power supply test, shorten the testing time of server motherboard hardware and error correction. HPCTS has been in charge of the department. The approval and support of the head of Intel PEG-BIOS department and the director of Intel PEG-BDE (Board Design Engineering) have entered the trial stage of program adjustment at present. Cyclic power supply test is the first and most important test in the test process of server motherboard. Different types of cyclic power supply test can reflect the robustness of motherboard hardware, firmware (such as BMC,). The stability of BIOS and firmware of peripheral controller and its compatibility with operating system (Linux, Windows OS). The previous cyclic power supply test scheme was limited to a cyclic power supply test on a single server motherboard. Once there is a problem in the test, it is difficult to locate and solve the problem. The HPCT, which is independently developed by the author, can realize cross-platform test comparison and cross-type test comparison because it supports different types of cyclic power supply testing on multiple motherboards, so as to help test engineers locate the source of the problem more quickly and solve the problem. It saves the time of motherboard test and error correction. The cycle power supply test scheme includes the hardware and firmware design of HPCT test tool, and the software design of upper computer for testers. Modification of motherboard BIOS in accordance with Intel server cyclic power supply test standard and design of batch script for motherboard automatic detection software with cyclic power supply test. The knowledge that needs to be understood or mastered includes embedded hardware design, embedded firmware development, Microsoft Windows OS multithread programming, Intel server cyclic power supply test standard, Intel server hardware architecture and server BIOS architecture. BIOS development and Intel server hardware power down timing and so on. A considerable part of the knowledge comes from the internal data of Intel, such as server hardware architecture, system memory mapping, BIOS C language source code and so on, which can not be exposed due to NDA restrictions. In this paper, the whole scheme will be expounded from the point of view of design ideas and methods, the innovation of the scheme will be explained from the point of view of design principle, and the feasibility and development space of the scheme will be proved by the results of practical verification.
