How do you design a modern E/E (Electrical/Electronic) architecture for a vehicle platform?

E/E architecture design involves: Defining topology (distributed vs domain/zonal controllers), allocating functions to ECUs, designing network architecture (topology, protocols, bandwidth), power distribution strategy (fused outputs, smart fuses), wiring topology optimization, defining interfaces and communication matrices, and planning for technology evolution. Modern trends include consolidation into powerful domain controllers, zonal architecture reducing harness complexity, and centralized compute platforms. Key trade-offs include flexibility vs cost, processing distribution, and supporting software-defined vehicle features. Architecture must support 10-15 year vehicle lifetime including technology updates.
