摘要
Abstract
In order to meet the demands of testing physical transmission performance of CAN ( Controller Area Network) -bus, we propose a CAN-bus fault-testing system based-on FPGA ( Field Programmable Gate Array) , which detects faults through collecting physical layer waveforms. We first analyze the principles of the testing system , provide the design of the system, and then describe the implement methods of the key technologies, including the automatic identification of frequency, the frame extraction, the analysis of faults on bus and the data storage. Functional simulations were carried out on the fabricated testing system, experiments were also carried out. The results exhibit that the system can correctly identify the bus faults and output related information.关键词
