Abstract:The construction of an automatic test system based on the ATML standard is the future development direction of the automatic test system, and the description of the test information in accordance with the ATML standard is the key to construct an automatic test system. Analyze the background, purpose and framework of the ATML standard, and explain the content of each sub-element of the ATML standard, especially for the standardization of the test description component in the standardization of test information during the development of the test program. According to the above analysis, the application method of ATML in the automatic test system is given. It lays a technical foundation for the automatic test system to automatically generate test stimuli based on the description information of each component.
