Abstract:
This application discloses a controller area network (CAN) design and verification tool to identify periodic messages and sporadic messages that a control node is configured to transmit on a shared bus in a CAN design. The CAN design and verification tool can assign placeholders to a schedule table of the control node to define a message transmission schedule for the control node. The placeholders include at least one sporadic message placeholder configured to identify one of a plurality of minor time frames available on the shared bus for the control node to transmit any one of the sporadic messages. The CAN design and verification tool can determine a worst-case latency associated with delivery of a first one of the sporadic messages on the shared bus when the control node utilized the sporadic message placeholder to transmit a second one of the sporadic messages on the shared bus.
