Simulation Methods of Nuclear Electromagnetic Pulse Effects in Integrated Circuits

首先介绍集成电路互联线在电磁辐射下输出响应的计算方法,包括时域有限差分法和传输线矩阵法;基于良好屏蔽近似,讨论电磁拓扑理论在集成电路核电磁脉冲效应仿真中的适用性;最后,结合互联线输出响应的计算方法,提出集成电路核电磁脉冲效应基于电磁拓扑的仿真方法。

In the paper the ways to compute the response of transmission line （ TL） illuminated by electromag-netic pulse （ EMP） were introduced firstly , which include finite-difference time-domain （ FDTD） and trans-mission line matrix （ TLM）;then the feasibility of electromagnetic topology （ EMT） in ICs nuclear electromag-netic pulse （NEMP） effect simulation was discussed;in the end, combined with the methods computing the re-sponse of TL , a new method of simulate the transmission line in IC illuminated by NEMP was put forward .
