Original Abstract
The paper deals with the implementation details of a symbolic analysis of complex circuit models including the transistor level in the symbolic simulator SNAP. Recent advances in approximate symbolic analysis enable applying the analysis to circuits with tens of transistors. The SNAP simulator allows combining high-level behavioral models with transistor-level ones. All models are defined in a text-based library, which can be easily extended by the user. Each model in the library is represented by its matrix-stamp for the Generalized Modified Nodal Analysis. Two algorithms of approximate symbolic analysis are implemented. The first algorithm simplifies the circuit model and the second simplifies the generated formula. The paper describes the modeling style and a procedure for automated extraction of small-signal models of semiconductor devices from the output file of the PSpice simulator.
Keywords
