derstand the working principle of automobile circuits, and improve learning efficiency. Take the circuit design software Multisim13 as the platform to learn the use of circuit simulation software. Taking the relevant circuits of automobile lighting system and lighting signal system as the research object, the lighting and signal control circuit are designed through Multisim software to realise the lighting and off of automobile steering lights, danger alarm flashes, fog lights, widening lights, headlights and reversing lights.The working principle of automobile headlights, fog lights, steering lights and other circuits is designed and analysed in detail, and the operation demonstration of normal working conditions is simulated; the fault point is set up through simulation to demonstrate the fault phenomenon; according to the exhaust process, through Multisim simulation software, the simulation process is carried out. Under the condition of hypocritical simulation, we should be familiar with the process and method of automobile circuit discharge, ensure students understanding and mastery of automobile circuits, exercise students thinking, and improve learning efficiency.

一、引言
电子设计自动化是现代电子工程领域的一门新技术,它是利用计算机对电路工作原理进行仿真设计,Multisim就是电子设计自动化的一种。Multisim13.0软件是将虚拟元件引入到仿真软件中,使用软件操作就像实际操作实验一样。不仅降低了学习的成本还提供了各种电源、元件、模拟器件,还有万用表、示波器等测量工具。利用Multisim13.0仿真软件进行汽车电路的设计,通过仿真呈现电路工作过程,便于理解汽车电路的工作原理。为了提高对电路故障的排查、诊断、修复能力,在没有实际设备的情况下,通过虚拟仿真,在电路中设置故障、通过检测分析故障,练习故障排除,熟悉排故流程。通过仿真的方式,具有操作简单、易懂、安全、节约、环保等优点,可以有效的帮助学习者,掌握相关电路知识。已经有不少成功的案例,比如:
2022年,覃缓贵教授运用了Multisim仿真软件设计了延时断电开关的仿真实验,通过了Multisim13.0的软件仿真实验结果证明,实现了节电保护的效果。
