Claim Text:
1. A method comprising: receiving, by a computing device, parameters associated with a controller area network (CAN) having multiple controllers configured to transmit messages over a shared bus based, at least in part, on priorities associated with the messages, wherein the parameters are configured to identify that at least one of the controllers is configured to internally order a subset of the messages for presentation to the shared bus with priority inversion, and wherein the parameters identify each message available to be delivered over the shared bus, a frame period on the shared bus, a transmission time of a frame on the shared bus, and an offset between an initiation of message delivery and a start of the frame period; and determining, by the computing device, a delay in delivery of a target message through the controller area network caused by the priority inversion based, at least in part, on the parameters.
