<p>PURPOSE: To find nodal point voltage of an electric element and a circuit at high speed by forming a single block by gathering nodal point equations related to respective wirings with respective wirings of an electrical network, and repeatedly finding the nodal point voltage per block unit. CONSTITUTION: Respective terminals of resistant elements connected with respective wirings of line directional wiring and line directional wiring are formed as a single group. Respective terminals of resistant elements connected with respective wirings of row directional wiring and row directional wiring are formed as a single group. An initial value is set in respective terminal voltages of the respective groups, and nodal point voltages of the respective terminals of an (n)th group are calculated and renewed on the basis of nodal point analyzing simultaneous equations related to nodal point voltages of the respective terminals of the (n)th group in the respective groups and initial values of nodal point voltages of respective terminals of a group except the (n)th group. Nodal point voltages of the respective terminals of the (n)th group are calculated and renewed on the basis of nodal point analyzing simultaneous equations of the (n)th group and the nodal point voltages of the respective terminals of the group except the renewed (n)th group. The fact that the nodal point voltages of the respective terminals before and after renewal are compared with each other for convergence is judged.</p> |
