Failure Mode and Effect Analysis (FMEA) is a useful tool to aid in the detection and prevention of product defects. FMEA's are used throughout the automotive industry to facilitate the delivery of failure-averse modules to customers. This paper applies FMEA techniques to generic stand-alone Controller Area Network (CAN) chips. The CAN protocol, developed by ROBERT BOSCH GmbH, offers a comprehensive solution to managing communication between multiple CPUs.Device-level FMEA's investigate the system-level impact of electrical abnormalities on a pin-by-pin basis. Conditions such as pins shorted to power or to other pins are evaluated for their effect on the system. Severity levels are also estimated.An FMEA for generic stand-alone CAN devices must consider failure modes for various pin types: power, clock, clockout, interrupt, mode selection, CAN bus, I/O ports, and address/data bus. In addition, this paper discusses how CAN devices detect and respond to bus errors and explores how the system may utilize this information in an FMEA analysis.
