Summary:PURPOSE:To provide a circuit simulation device automatically retrieving a node to be a cause and emphatically displaying it on a display means when circuit simulation does not converge. CONSTITUTION:A node number extraction means 7 for extracting the number of the node not satisfying convergence discrimination conditions from halfway result data when a simulated result does not converge and a node retrieval means 9 for retreiving wiring on a circuit diagram corresponding to the node from net list data 4 and circuit diagram data 2 by using extracted node number data 8 and emphatically displaying the pertinent part of the circuit diagram on the display means 10 are provided. Also, the plural numbers of the node number extraction means 7 and the node retrieval means 9 are prepared corresponding to the respective different convergence discrimination conditions and emphatic display is performed in mutually different display colors.
