Abstract

To solve the test problems coming with the extensive use of the FlexRay bus in weapon systems, a multilevel test method combining tests in both bus protocol level and physical level is proposed in this paper. The simulation for nodes sending and receiving data is therefore achieved. In addition, the transmission medium of FlexRay bus can also be tested by outputting special signals, and the transmission quality in physical level is then evaluated. The software and hardware design and the test results showed that the multilevel test method designed in this paper can test and evaluate the transmission performance of FlexRay bus better, having the good application potential in the scheme design and integration test phase of weapon development.

Key words： FlexRay bus; bus test; PCIe architecture; weapon system
