Automated CAN Physical Layer Signal Integrity Verification
Technology Overview
Abstract
With today’s automobiles containing 70 or more electronic control units (ECUs), data communication is a crucial aspect of the vehicle electrical platform design. The Controller Area Network (CAN) is a widely deployed standard for these networked systems. This presentation discusses a new simulation-based automated analysis capability that engineers at Chrysler are leveraging to assure signal integrity for proposed vehicle network topologies. This flow includes spreadsheet entry of the network configuration, followed by automatic schematic generation, simulation and results measurement/verification. Parametric design analysis is also supported, so a configuration that is marginal or failing to meet performance specifications may be “dialed in” by identifying simple but effective parameter adjustments.
