Abstract

A system and a method for rapidly diagnosing bugs of system software are apply for rapidly localizing a system program fault that causes a system error and then feeding back to a subscriber. First, according to the subscriber'"'"'s requirement, a program of system fault analysis standard is preset and written into the system. Next, a plurality of fault insertion points is added into a program module of the system according to the subscriber'"'"'s requirement for the precision of the fault analysis result. Then, fault management information is generated at the fault insertion points during the running process of the system program, and the management information is monitored for collecting relevant system fault data. After that, the collected system fault data is analyzed in real time through the program of system fault analysis standard, so as to obtain the minimum fault set for causing the system error.
