| Abstract: | Analyzing the Real-Time performance of the CAN bus is one of the focuses in applications. The model of the messages in the communication network was presented, the calculation of time characteristic parameters of the messages transmit based on Fixed-Priority Scheduling and the necessary condition of schedulability were analyzed. Then, the design of performance analysis software package was described. Finally, an application example was given and the test result of the load ratio on the bus was got, which shows that the package is a powerful offline analysis tool. |
