Achieve scalable, flexible in-vehicle networking

Keywords:FPGA? networking? in-vehicle?

Over the past decade, in-vehicle networking architectures have become much more complex. Although the number of in-vehicle networking protocols has been reduced, the number of networks being deployed has increased dramatically. This leads to network architecture scalability issues and semiconductor device optimization to match each application and network's actual needs.

FPGAs, once thought of as a solution for development purposes only, have come down in price to the point where many issues can be resolved and put into production at a lower overall system cost than the traditional ASIC or ASSP solution. All of the major FPGA suppliers to the automotive market are now ISO/TS16949-certified, making PLDs a mainstream technology in the automotive market.

During the last 10 years, many proprietary OEM automaker networking protocols have made way for standardized global protocols like CAN, MOST and FlexRay. This lets semiconductor vendors concentrate on building devices with these specific protocols built in, bringing more competition and lower prices to tier-ones and more module interoperability at the OEM level. However, in today's vehicle electrical architectures, both OEMs and tier-ones still struggle with many issues.
