CAN is the most widespread communication protocol in today's automotive

industry. The latest technology, FlexRay has already become widespread as fault

tolerant applications are expected in the industrial area. Gateway devices provide the

transition through the different kinds of bus systems. This Thesis aims to develop a

hardware device like those.

The first three chapters cover the presentation of the most widespread

communication system types including CAN, LIN and FlexRay and their comparison at

the aspect of the gateway hardware have to be implemented. The Thesis contains the

detailed overview of the development process. It begins with the choice of

microcontroller architecture and the appropriate device. This part is followed by the

selection of integrated circuits provide power supply, and bus transceivers for CAN and


Then there is a brief description of applied CAD system followed by the

components' intake to its library manager. After that the detailed description of

schematic can be found, which is followed by presentation of PCB's topology and layer

stack-up. The strict constraints in routing some critical integrated circuits are also

detailed there.

At the end there are some chapters about the first powering up the device

followed by the future aims and fields of application which can be performed by further

development of firmware and software.
