<p>PROBLEM TO BE SOLVED: To provide a simulation method and a simulator which improves the probability of satisfying the convergence conditions of Newton repetition in the simulation method suited to a simulator for analyzing an event by using Newton's method. SOLUTION: A simultaneous equation is prepared with the node potential of each node of an analyzing object circuit. A circuit simulation method calculates the simultaneous equation by using the Newton's method (step S14) to perform DC operation point analysis. When the convergence condition by Newton repetition is not satisfied (step S15), a random number is multiplied to the value of a node potential which is not convergent to set a new initial value (step S20), to recalculate the simultaneous equation. This series of operation is called a fluctuation method.</p> |
