ABSTRACT:
A method of simulating the operation of a circuit utilizing voltage or current data obtained from measurements of actual samples of each of the circuit components. The actually measured voltage or current data is employed to mathematically analyze operation of the circuit. In this process, each circuit component is characterized as one or more of a voltage controlled voltage source, voltage controlled current source, current controlled voltage source and current controlled current source. After such characterization, a trial operating point is selected and values of current or voltage between actually measured data points are determined and linearized circuit equations are established with spline equations. The linearized equations are solved. The steps are repeated with a new trial operating point in accordance with a Newton-Rhapson iterative technique until the solution of the linearized equations is within a predetermined range.
