Design of a Plug'n'Play analysis interface for the communication protocol Flexray

Abstract

This thesis is a report of our evaluation of the possibility to create a prototype of a Plug’n’Play hardware tool for analysing a Flexray Communications Systems network. The design of this tool was made with the intent of using an FPGA for decoding transmission and an ARM-processor for transmitting data, creating a basis for development. We design the prototype to only capture data sent on the network. The theory was that this would form a basis for further analysis. Due to hardware malfunction in the later parts of the project, no actual test of this theory could be done. Our results suggest that only using an FPGA for analysis and transmitting data is enough and additional analysis could be done on a different tool or using software on a larger system, such as a PC.
