Accurate can-based distributed control system simulations

摘要

Embodiments of the present invention are directed to a computer-implemented method for simulating a plurality of electronic control units (“ECU”s) in communication over a simulated bus. The method includes simulating an operation of a first ECU and an operation of a second ECU and performing arbitration at a packet-level granularity at a packet transmission start point with respect to a first packet sent to the simulated bus by the first ECU and a second packet sent to the simulated bus by the second ECU. The method identifies an initially winning ECU in the arbitration and a zone from the packet transmission start point to a bit where the initially winning ECU is determined to win based on the arbitration and continues the simulation of the operation of the first ECU and the operation of the second ECU to the end of the zone.
