The simulation software is introduced (including the algorithm, principle) the simulation software (including the algorithm, principle) The following statement: all from the network With the increase of wireless and wired to the development and design of higher frequency and circuit complexity, the simulation of high frequency electromagnetic field, due to the neglect of the high order mode of transmission caused by simulation error. In addition, the traditional model of the equivalent circuit analysis method, error and frequency dependent capacitance and inductance components caused by equivalent model. For example, in the analysis of microstrip line, many error prone passive mode is due to microstrip or stripline crossover, ladder, bending, open slot, etc., in this case the multimode transmission. To this end, usually by full wave electromagnetic simulation technique to analyze the circuit structure, through circuit simulation and accurate discontinuous mode S parameters. The numerical solution of the EDA simulation software and the electromagnetic field is closely related to the different simulation software is simulated according to the analysis of different numerical methods. Usually, the numerical solution is divided into explicit and implicit algorithm, implicit algorithm (including frequency domain methods all) with the increasing of the problems, showed a strong nonlinear. Display algorithm (such as FDTD, FIT method in dealing with problems of storage capacity and reasonable time. This article makes a classification according to the numerical methods employed by electromagnetic simulation, discusses
