The invention relates to an analog storage test board system based on an intelligent electric meter software reliability test platform, and a test method therefor. The system comprises a detection computer, an analog storage test board, a tested unit, an interface A and an interface C, wherein the detection computer performs information interaction with the analog storage test board through the interface A; and the tested unit performs information interaction with the analog storage test board through the interface C. The test method comprises five steps of analyzing a read-write operation of an analog storage chip of a storage analog board FPGA, analyzing the communication protocol between an ARM chip and the storage analog board FPGA, executing the comprehensive program on the analog storage test board, and the like. The analog storage test board provided by the invention is combined with the ARM and the FPGA; the function of the actual storage chip is simulated through the FPGA hardware logic; and therefore, the problem of relatively low information interaction speed between the ARM and the storage chip module, and the problem that the states, such as failure and the like, required by test cannot be simulated are solved.
