Abstract:
This paper discusses the pre-condition methods (that is, the ILU methods) for solving the linear system in semiconductor device simulation.First, with the introduction to the theoretical foundation of ILU methods, the importance of applying pre-condition methods to solve the iterative convergence problem of linear equations is illustrated. Then, the ILUV methods, which were developed from the ILU methods are introduced. Based on the theoretical study and algorithmic analysis of those ILU and ILUV methods, the ILUVP method, which maintains the merits of those two methods and solves the problem that the selection of the parameter ψ in the ILUV method can not meet the different demands for both calculating amount and the convergence rate, is put forward. Finally, through an example of a drift-and-diffusion equation with steep distribution, the feasibility and effectivity of this algorithm are proved.
