Today’s electronic automotive designs include a combination of analog, digital, and serial bus signal content. Embedded automotive designs usually consist of distributed microcontroller-based networks with serial bus communications such as CAN, LIN, MOST, and/or FlexRay. Automotive design engineers have traditionally used oscilloscopes to test their analog signals — logic analyzers and trace debuggers to test their digital parallel I/O signals — and protocol analyzers to test and debug serial buses. But a class of measurement tool known as a mixed signal oscilloscope (MSO) may be a superior tool allowing for time-correlated testing of all three types of signals in one instrument. Using an example of an electronic automotive design utilizing CAN serial communication, this paper not only discusses the various MSO performance characteristics required to test and verify this type of design, but also shows a debugging methodology to uncover a random and infrequent signal integrity problem on the differential CAN bus.



Intended Audience:


This paper is intended primarily for embedded hardware designers developing various automotive electronics that utilize CAN, LIN, or FlexRay serial communication. Although this paper presents an example of debugging an automotive application, the basic troubleshooting concepts presented in this seminar can be applied to a much broader area of embedded design — not just automotive.
