Debugging automotive serial buses using an Agilent InfiniiVision Series oscilloscope (Italiano)
1 Hour | Webcast - recorded | Where & When
To improve efficiency of vehicle communication and control, all of today’s automotive designs employ a variety of serial buses including I2C, SPI, LIN, CAN, and FlexRay. Unfortunately, serial bus communication is often susceptible to signal integrity problems caused by the naturally harsh environment found in automobiles, including signal interference from ignition systems and random noise, which can sometimes create errors during critical communication cycles. Although serial bus protocol analyzer are a great tool for testing and monitoring the higher level protocol and application layer transfer of data, they tell you nothing about the integrity/quality of your automotive serial bus signals (physical layer).
This web seminar will begin with an overview of the timing and protocol structure of the LIN, CAN, and FlexRay buses. But since FlexRay is the new bus on the block, we will spend most of our time learning about the hierarchical network structure of FlexRay. We will then show how an oscilloscope can be used to trigger on and decode these buses in order to time-correlate data transfer information with the physical layer.
Hardware-based decoding and segmented memory acquisition with automatic frame decoding are some unique characteristics of Agilent’s InfiniiVision series oscilloscopes. We will talk about why faster decoding is important to capture random errors, and how segmented memory can be used to capture more data than is possible with conventional oscilloscope acquisition memory.
We will wrap-up this web seminar with some probing recommendations, as well as required oscilloscope performance (bandwidth and sample rate) to debug the physical layer of automotive systems.
Who should attend?
Engineers and technicians that design, debug, and/or test automotive ECUs that serially communicate over the LIN, CAN, and/or FlexRay buses. In addition, this web seminar would be of interest to anyone who integrates ECU and serial networks within the vehicle, and needs to verify the signal integrity of the physical layer of these buses.
