摘　　要：计算机故障诊断系统是诊断计算机硬件故障的一个强有力的工具。本系统基于PCI总线传输原理,以FPGA作为控制核心。通过在FPGA上编程搭建信号采集与处理电路,根据计算机自身的加电自检原理,采用VHDL硬件描述语言在FPGA上设计硬件电路实现数据存储,分析,提取等一系列处理,通过51单片机控制液晶实现计算机硬件故障的汉字。当计算机主板上的硬件发生故障时,能迅速诊断出故障发生的部件,提高计算机维修效率。The computer hardware diagnosis system is a powerful tool to diagnose computer hardware failure. This system based on PCI bus transmission principle,and with FPGA as the control core. VHDL hardware description language design on the FPGA hardware circuits for data storage, analysis, extraction of a series of processing by the signal acquisition and processing circuits on the FPGA programming structures, according to the computer＇s own power-on self test principle, and then through the 51 single-chip implementation Chinese characters on the LCD display in the form of computer hardware failure. When on the computer motherboard hardware failure, we can quickly diagnose the failure parts, improve the efficiency of computer maintenance.
