摘　　要：LIN虽然为传统总线,但仍大量应用在汽车、智能家居和工业控制等领域。基于此,设计一种高可靠LIN控制器IP。基于AMBA APB3.0标准接口的IP不仅实现了LIN协议规定的数据收发、网络管理等功能,还增加了大量可靠性和安全性相关功能,如错误监测、看门狗、环回自测试、显性电平监控等,通过这些可靠性措施使得IP达到ASIL-B级技术指标要求。针对IP搭建仿真验证环境,完成了SoC级仿真和FPGA原型验证,并基于国内某流片厂商110 nm工艺,完成了逻辑综合,生成了Verilog格式的网表文件。通过测试和逻辑综合分析得出:所提出的控制器IP性能满足协议和设计需求,在110 nm三温三压极限条件最高频率可达625 MHz,逻辑单元约为5 950,等效逻辑门约为10 554,面积为34 676μm2。该IP功能优于对比文献,可直接集成到微控制器MCU、SoC和FPGA设计中,减少设计周期和产品上市时间。LIN(local interconnect network) is a traditional bus,but it is still widely used in automotive,smart home and industrial control fields.On this basis,a highly reliable LIN controller IP is designed.The IP based on the AMBA APB 3.0standard interface not only implements the data transmission and network management functions specified by the LIN protocol,but also adds a large number of reliability and security related functions,such as error monitoring,watchdog,loop back self testing,explicit level monitoring,etc.The IP can meet the ASIL-B level technical specifications requirements after these reliability measures.The simulation verification environment for IP is built to complete SoC level simulation and FPGA prototype verification,and the logic synthesis is completed based on a domestic chip manufacturer's 110 nm process,and the Verilog format netlist files are generated.fter testing and comprehensive logic analysis,it is concluded that the proposed controller IP performance meets the protocol and design requirements.Under the 110 nm three temperature and three pressure limit condition,the highest frequency can reach 625 MHz,the logic unit is about 5 950,the equivalent logic gate is about 10 554,and the area is 34 676 μm2.This IP has better functionality than the comparative literature and can be directly integrated into microcontroller MCU,SoC,and FPGA designs,reducing design cycles and product launch time.
