Developing an automotive electrical distribution system Part 1: System designBy Nigel Hughes, Mentor Graphics February 21, 2007 - automotivedesignline.com The electronic content of a modern car has become one of the key brand differentiators in the market place. Alongside the obvious problems in ensuring that the latest technologies are available to be included is making sure that the associated systems supporting deployment into the vehicle can be developed and integrated into the final production vehicle. Any problems are compounded by the pressure of ever decreasing design cycle times. As can be seen from the graph below, cycles have now been reduced to between 24 and 18 months, with a clear goal for most OEMs to reduce this to 12 months by 2010. Within this cycle the electrical distribution system supporting the electronic content must be designed, validated, and deployed. Doing this is increasingly dependent on developing new processes and tools to support those processes.  In order to preserve a reasonable margin, automotive OEMs must also see that an appropriate return is gained from the technology, by specifying vehicle models with an appropriate set of options in order to support accurate pricing. Recently the market has witnessed a dramatic increase in the amount of optional content in vehicles. This trend pushes the need to make the latest technologies available, whilst ensuring basic car models are still available in an extremely price competitive market.
