GPGPU-FDTD method for 2-dimensional electromagnetic field simulation and its estimation

For signal/power integrity analysis of the high density packages and printed circuit boards, the FDTD (Finite-Difference Time-Domain) method has been widely used. In order to apply to large-scale problems, a variety of acceleration techniques are required. This paper describes a GPGPU-FDTD (General Purpose computing on GPU (Graphic Processing Unit)-Finite-Difference Time-Domain) method for massively parallel electromagnetic field simulation. Finally, it is confirmed that GPGPU-FDTD method shows the high-performance when the computational algorithm is programmed suitably for the architecture of GPU.
