Given the recent strong growth in automotive technology requirements and the increase in bandwidth needed for applications such as ADAS and autonomous driving, it is necessary to create solutions to manage the transport of this enormous amount of data between the various devices in the vehicle. As a result, numerous companies are developing devices capable of handling the new technologies and protocols required for this. However, equipment that works with the same technologies and bandwidth to record the exchanged traffic without losses is also needed for testing and validation tasks. Therefore, this project, developed at Technica Electronics Barcelona, consists of the study and development of a network tap system prototype able to capture multigigabit ethernet links (2.5Gbps, 5Gbps and 10Gbps) and GMSL2/3 serialized video links. The prototype allows snooping the traffic transmitted over these channels (keeping its original communication intact) and is able to send it to a data logger with its own standardized protocol for storage and further processing and validation through 10Gbps SFP+ ethernet interfaces. The project, based on a Zynq Ultrascale+ MPSoC architecture, also aims to provide an overview of the main concepts involved in the development and debugging of ethernet and video capture systems on Xilinx All-Programmable devices, with a special focus on gigabit transceivers.
