Abstract

The invention provides an SOA test method, system and device for a switching power supply MOS transistor and a readable storage medium. The method comprises the steps that an SOA test platform based on Python is constructed; the SOA test platform based on Python is started, and an independent test thread is created; after the test thread is created, an internal definition function is called to complete calling of test resources, and a test scene is executed; in the process of executing the test scene, if user interruption is received, processing is performed preferentially; after the current test scene is ended, test data and recommended data calibration are generated, and data calibration of the test data is generated according to the recommended data calibration; whether all the current test scenes are tested or not is judged; and the test data of all the test scenes is analyzed and calculated, and a test result is generated. The SOA automatic test of the MOS transistor is realized, an auxiliary analysis tool of the test result is provided, and the possibility of errors of the test result is reduced.

Description

technical field

[0001] The invention relates to the technical field of MOS tube safety testing, and more specifically relates to an SOA testing method, system, device and readable storage medium of a switching power supply MOS tube. Background technique

[0002] As a representative of new semiconductor devices, MOS transistors are widely used in server power systems as important switching elements. In order to ensure that the MOS tube can work safely, it is particularly important to perform an SOA test on the MOS tube. The SOA test is a functional test to verify whether the MOS tube is within the safe operating area (Safe Operating Area, SOA). In the R&D cycle of the server, there are many test items and it takes a long time. Under the background that the server R&D test is fully automated, SOA test is an important test item, and it is very necessary to realize automated testing.

[0003] Currently, the SOA testing method of MOS tubes is manual testing. The specific proce...
