[Abstract]:As an important storage medium, memory has been widely used in computer, mobile electronic equipment, aviation industry and other fields. Single particle effect in space has a great impact on the stability and reliability of aerospace electronic devices. It is more and more important to ensure the functional stability and high efficiency change of high reliability space memory. In order to verify the function and reliability of spaceflight memory, it is necessary to do it in the ground simulated space experiment environment. Therefore, it is very important to design and develop a test system which can be used to test the high reliability memory in the ground simulation space experiment environment. In this paper, based on the background requirements of memory testing in the ground simulated space experiment environment, this paper analyzes and introduces the memory testing method, puts forward the design scheme of the system under the test environment, and makes the corresponding structure design and implementation. The high reliability memory test system is perfected. The research and design work of this paper includes: firstly, this paper introduces the development direction of automatic test system and the concept of virtual instrument, then analyzes the fault model of memory and common test algorithms. Secondly, the structure design and module planning of the system are analyzed in detail according to the test requirements under the ground simulation space experimental environment. Then it introduces the test module of FPGA algorithm based on the test requirement of Verilog HDL, and finally analyzes the realization process of the control interface design of the system with LabVIEW graphical programming language in detail. And perfect the automation control of the whole system. The test system designed in this paper has not only been verified by the general laboratory but also measured in the ground simulated space experimental environment. The system implementation method of the integrated circuit test technology and virtual instrument technology used in this paper is discussed. The expansibility and operation flexibility of the system are improved.
