Abstract

This paper describes a new fully automated, behavioral modeling tool, Ascend, which starts from the netlist description of the circuit and generates differential algebraic equation (DAE) based behavioral models. The physical modeling methodology in Ascend makes it possible to represent the nonlinear behavior of circuits. A modeling example is given for a better illustration of the behavioral modeling tool. Simulation results have demonstrated that both accuracy and efficiency can be achieved from the behavioral modeling tool.
