Abstract

An embodiment of the present invention provides a program execution sequence diagnosis method and system based on an independent clock programmable logic device, wherein the method includes: acquiring the next program stage flag of the diagnosed program detected by the processor; Get the correct next program stage flag in the window, if not, it is determined that the execution sequence of the diagnosed program is abnormal. Through the method and system for diagnosing the program execution sequence provided by the embodiments of the present invention, the diagnosis of the program execution sequence of the program to be diagnosed is more reliable.

Description

technical field [0001] The invention relates to the technical field of fault diagnosis, in particular to a program execution sequence diagnosis method and system. Background technique [0002] During the running of the software program, there may be an abnormal execution sequence of the internal program. When the program execution sequence of the software program is abnormal, the system may not be interfered by the external electromagnetic field, causing the program to run away and the normal operation of the program to be interrupted. Interruption, or program crashes due to internal cross-border, stack overflow, deadlock and other factors due to software design problems, these may lead to unpredictable results of the software program during runtime, and endanger the determinism and security of the system. In order to avoid this hazard, the system needs to be able to diagnose whether the program execution sequence of the program is abnormal. [0003] At present, software is...
