Consider ways to improve the performance of automation systems schematic design through data compression techniques fixed format. It is shown that a distinctive feature of the methods is the impossibility of a fixed format included in the description of additional non-zero elements. This property of the methods fixed format eliminates the possibility of their direct application to process information for solving systems of equations by any numerical method, due to the inevitable emergence of new non-zero elements in the process of this decision. To be able to take account of new non-zero elements in the compact description of the simulated system is proposed to conduct clarifying the format based on the topological analysis of the image of the simulated circuit. A description of the two-stage implementation of the sparse matrix handling procedures by sequential execution of the topological and numerical analysis is given. The practical implementation of the two-stage compression process can significantly improve the efficiency of automation of circuit design.
