Embodiment Construction

[0013] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0014] A kind of server main board power-on / off test method based on timing monitoring of the present invention is described in more detail below: the specific steps are as follows:

[0015] a) The R&D engineers first group and integrate the key physical signals involved in sequential logic with programmable logic controllers according to the power-on sequence requirements of the motherboard;

[0016] b) Build the power-on sequence coordination requirements of the motherboard into the DSP, that is, the time sequence and trigger requirements of each sequence signal are implemented in DSP software language;

[0017] c) The programmable logic controller transmits the collected timing signals to the DSP data processing center, and the DSP judges the actual values ​​such as the time sequence and trigger requirements of the participating signals according to the pre...

Abstract

The invention provides a method for testing start and stop of a server mainboard based on time series monitoring. The method comprises the following specific steps that 1) a development engineer integrates key physical signals participating in temporal logic in different groups by a programmable logic controller at first according to requirements on power sequence of the mainboard; 2) matching requirements on the power sequence of the mainboard are met in a DSP (digital signal processor) in a built-in manner, namely time sequence and triggering requirements of various time series signals are met by DSP software language; and 3) the programmable logic controller transmits the acquired time series signals to a data processing center of the DSP, and the DSP judges actual values such as time sequence and triggering requirements of the various participant signals according to a preset time series requirement, and then judges whether the time series requirements are met or not.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to a timing monitoring-based testing method for switching on and off a main board of a server. Background technique [0002] Today's server products, the server needs long-term uninterrupted operation and stability, and the reliability requirements are constantly increasing. In order to ensure the stable startup of the system, during the development and testing process of the server motherboard, a strong test method is required to strictly test the system. In particular, the timing monitoring during the boot process needs to focus on testing. [0003] The server motherboard has strict requirements on the boot sequence. Any difference in timing will cause system initialization problems and other derivative problems. Therefore, timing monitoring must be included in the reliability test in order to better realize the high reliability of the logic timing function of the entire moth...
