| Outline of Final Research Achievements |
The purpose of this research is high-speed and high-precision electromagnetic and circuit mixed-mode analysis for predicting signal integrity, power integrity and electromagnetic interference for high density circuit board in mobile devices and high performance servers. In this research, the theoretical construction of connection algorithm between electromagnetic analysis by DGTD method and circuit analysis based on SPICE and Leapfrog method was done. Also we developed a solver based on above algorithm. As an application example of the developed mixed solver, we verified the signal integrity analysis of the interconnect. We also verified the improvement of analysis accuracy by implementing parallelization by GPGPU and increasing the number of divisions of the interconnect model.
