摘　　要：为解决车载ECU和网络开发中评测在复杂干扰工况下的系统行为是否符合协议规范,设计了基于片上系统(SoC)的CAN网络干扰测试设备。以Altera公司FPGA为基础,通过Verilog HDL语言描述CAN通信物理层总线失败、总线电平异常及线缆长度下位机实施系统和上位机用户配置界面。通过实践搭建CAN通信网络,并运用本文设计实施干扰表明,设计能够有效灵活的向CAN通信网络嵌入干扰,考证节点和网络的可靠稳定性。Design a kind of interfere testing equipment in CAN network based on a chip system to solve the vehicle ECU and evaluation in thecomplex interfrenee （ondilions in the development of network. Descript the CAN communication bus failure, the physical level anomalies and cable length under a machine implementation of the system and PC user configuration interlace by VerilogHDL on the base cff FPGA. Build the CAN netxrork, implement the interfierence of the design in this network. The results indicated that the design can embed interference into CAN network efikeiivclv and flexibly, reliability and stability of nodes were proved.
