Method of storing jumping change signal and device thereof

Abstract

The application provides a method of storing a jumping change signal. The method includes: detecting a jumping change of a first signal of a server by a monitoring module, and sending a signal jumpingchange indication to a buffer module, wherein duration of the signal jumping change indication signal is at least one clock cycle, and jumping changes of the first signal include a change from a high-level signal to a low-level signal and a change from the low-level signal to the high-level signal; caching the first signal by a cache module according to the jumping change indication; and storingthe cached first signal to a storage card by a storage control module. Therefore, according to the method provided by the embodiment of the application, the jumping change signal of the server can beeffectively stored, detection and storage on key signals are realized, and when the server fails, the jumping change signal stored in the card can be stored simply and quickly to carry out analysis torealize troubleshooting of the server.

Description

technical field [0001] The present application relates to the field of computers, and more particularly, to a method and device for storing transition signals. Background technique [0002] During the debugging and use of the server, sometimes problems such as shutdown and downtime may occur due to failures. In order to troubleshoot these problems, debuggers need to know the state of each signal when the fault occurs. [0003] In the prior art, debuggers can use an oscilloscope to monitor corresponding signals, and try to reproduce the fault, and check whether the monitored signal is abnormal when the fault occurs. But this way is inefficient. [0004] A Baseboard Management Controller (BMC) can monitor some important signals and record them in a log, but the important signals it can record are limited. [0005] In addition, in the prior art, there is also a design method in which a server integrates a Microcontroller Unit (MCU) and connects a monitoring signal to the MCU...

AI Technical Summary

Problems solved by technology

However, the MCU needs to continuously load and execute instructions, and this type of device has the risk of program running to death.

And it takes a while to start the MCU, which may cause the MCU to fail to monitor the signal transition at some point

[0006] Therefore, the prior art cannot effectively store the jump signal of the server
