  4. Abstract:
  5. This paper evaluates the error propagation and its effects in babbling idiot failure in a FlexRay-based network. The evaluation is based on about 35680 bit-flip fault injections inside different parts of the FlexRay communication controller. To do this, a FlexRay communication controller is modeled by Verilog HDL at the behavioral level. Then, this controller is exploited to setup a FlexRay-based network composed of four nodes. Nodes in this experiment are considered in two forms: 1) node without bus guardian, 2) node with bus guardian. The results of fault injection show that in first form about 4.57% of faults lead to the babbling idiot failures. Also in second form about 0.75% faults lead to babbling idiot failures. After this experiment and evaluation of the results, one improvement in the bus guardian is done. With this improvement, the results show that babbling idiot failures are eliminated completely
