FPGA Prototype Verification of FlexRay Communication Controller Chip

FlexRay is high-speed, and its speed is several times higher than that of other vehicle backbone networks. It can effectively apply the simplified distributed control algorithm, implement the control mechanism with higher safety requirements, or replace the hydraulic system with an electronic control system. It can be used as the backbone network of the new generation automobile internal network. FlexRay communication controller chip makes it easy to integrate FlexRay into MCU based applications. Provide full system redundancy to meet the reliability requirements of the new safety system. MFR4310 is a mature FlexRay communication controller chip, and the function of NT4310 is compatible with MFR4310. In order to carry out the prototype verification of NT4310 chip, an FPGA prototype verification platform based on FlexRay bus architecture is developed. The process, verification environment and verification results are described. Experiments show that the platform and the corresponding verification process greatly improve the verification efficiency, shorten the whole design verification cycle, and provide a reliable guarantee for the successful chip delivery.
