Abstract:
1. A circuit simulation system, comprising: a storage section configured to store a circuit data, an analysis condition data, and an output data; an initial data setting section configured to read out the circuit data and the analysis condition data from said storage section and set an initial data and a convergence condition for a solution calculating process based on the circuit data and the analysis condition data; a processing section configured to generate a circuit equation to each of a voltage variable and a current variable based on the circuit data, and execute the solution calculating process based on the initial data to calculate a solution; a convergence determining section configured to execute a convergence determining process of whether or not the solution meets the convergence condition, on the voltage variable; an output section configured to store the solution into the output data when the solution is determined to meet the convergence condition; and a repetition control section configured to control said processing section to calculate a next solution by using the solution from the processing section as initial data, when the convergence determining section determines the solution does not meet the convergence condition.
