2.10 Nonlinear Symbolic Approximation

The linear simplification techniques implemented in Analog Insydes proved to be very effective and powerful. As of version 2, simplification routines for nonlinear circuits have been added to Analog Insydes. They are able to reduce the complexity of symbolic nonlinear differential-algebraic equations systems (DAE) with automated error control and can be used, for example, for behavioral model generation.

Section 2.10.1 describes the main principles of the nonlinear simplification techniques in Analog Insydes. Section 2.10.2 shows their application on an example.
