This article presents an efficient procedure allowing to increase the final accuracy of the electronic circuits simulation. To obtain Transient Analysis of a nonlinear circuit the simulator needs to perform various algorithms, from an evaluation of initial DC state through a nonlinear iterative algorithm, to a numerical integration. These complex computations have to be implemented effectively with regards to memory and processor usage. Direct implementation of arbitrary precision types can directly lead to increased simulation accuracy but also significantly decrease simulation performance. As a compromise, we suggest using an additional algorithm based on Newton Iteration method for the solution of matrix inversion. The method was modified to be comparable to direct LUF solver.
