| Abstract: | In order to meet the demands of testing physical tra nsmission performance of CAN(Controller Area Network)-bus,we propose a CAN-bu s fault-testing system based-on FPGA(Field Programmable Gate Array),which det ects faults through collecting physical layer waveforms. We first analyze the principles of the testing system,provide the design of t he system,and then describe the implement methods of the key technol ogies,including the automatic identification of frequency,the frame extraction,the analysis of faults on bus and the data storage.Functional simulations wer e carried out on the fabricated testing system,experiments were also carried ou t.The results exhibit that the system can correctly identify the bus faults and output related information. |
