CAN WAVEFORM SIMULATION DEVICE AND METHOD, AND CAN WAVEFORM TRANSMITTER

摘要

Disclosed are a CAN waveform simulation device and method, and a CAN waveform transmitter. The method comprises: a CPU transforms a pre-simulated waveform into a frame sequence; send the frame sequence to a CAN transceiver; the CAN transceiver transforms the received frame sequence to obtain a simulated waveform; the CPU generates, according to frame information of the frame sequence, configuration information, and configures a CAN controller according to the configuration information; the CAN transceiver sends the obtained simulated waveform to the CAN controller; the CAN controller analyzes or outputs, according to the configuration information, the simulated waveform, compares, according to the output simulated waveform, whether the received simulated waveform is a pre-simulated waveform, and outputs the analysis result. By simulating different waveforms in different actual scenes or theoretical scenes, the present invention is used for diagnosing the functionality and the stability of a CAN bus and nodes.
