Title Hardware design of test adapter based on ATE platform
Abstract
With the rapid development of science and technology, more and more extensive application of electronic equipment, when once the circuit board of the electronic equipment failure, it will make the use of electronic equipment caused serious influence. Low traditional circuit board fault detection and diagnosis of technical efficiency , high cost , and require experienced staff to complete. In order to improve this situation, people design the ATE platform, but the ATE platform does not fully meet all the needs of detecting circuit board fault diagnosis.So this paper describes a test adapter,which based on ATE platform to improve the function of ATE platform and this test adapter is designed for a radar fault detection. This test adapter with AT91SAM9G20 ARM chip and the Stratix ® III series FPGA as the main processor ,and with FLASH, SSRAM, DRAM, DAC, ADC circuit to complete the adapter work.After designing the hardware schematic diagram and PCB, processing and assembling,we conduct the system testing. Finally the test results show that the test adapter to meet the design requirements.
