Usually gateway configurations have been based on non-standardized description formats. Unfortunately data exchange between different formats is inherently error prone and time consuming. A common description format was necessary and is found in the field bus exchange format. Fibex is an XML-based file format, the upcoming standard for network configurations, which combines information about every aspect of a complete in-car network including controllers, channels, frames and signals. Fibex is also the first standard to describe gateway configurations. Gateway implementations have proprietary internal formats in which they store their configuration data. Some routing information is stored as linked lists, while others are stored as executable code. An optimal gateway tool chain should be based on the Fibex configuration data of all connected networks and translate the routing information directly into the internal format of the target implementation. The development of the tool chain at Bosch followed the development of a hardware-accelerated multi-protocol gateway. Currently the gateway connects FlexRay with CAN networks. Support for other protocols, like LIN and MOST, are planned. This paper describes the gateway hardware, gateway related enhancements to the FIBEX standard and the implementation of the tool chain to generate configuration images for the developed gateway.
