Equation Formulation and Wavelet Collocation Based Automatic-Modeling for Analog Circuits

An automatic behavioral modeling method for analog circuits is proposed in this paper.To build the systematical behavioral model,firstly the systematical structural description is established by formulating the nodal algebraic equations,and secondly the behavioral description of all building blocks is established by wavelet collocation method.The behavioral model generation tool has been successfully developed. Models generated here are oriented to industrial standard analog hardware description languages. Models based on wavelet collocation method are more accurate than the ones based on polynomial approximation. Behavioral level simulation based on these generated models is faster than transistor level descriptions.
