(Section 3.6.4) allow for adding, deleting, or extracting netlist entries and changing node names,
respectively, in a comfortable way.
Statistics (Section 3.6.17) prints information on the contents of a Netlist or Circuit object.
Analog Insydes provides a predefined symbolic device model library (Chapter 4.3), which can be
extended by the user. Several commands allow for accessing the model data base (Chapter 3.3):
LoadModel (Section 3.3.6) loads a specific model from a given model library.
FindModel (Section 3.3.2) searches the default model library for a given name/selector pair.
GlobalSubcircuits (Section 3.3.4, Section 2.3.6) prints the name/selector pairs of all global
models currently loaded.
ListLibrary (Section 3.3.1) prints the contents of a specific model library.
Equations
Starting from Circuit or Netlist objects, circuit equations can be set up automatically in different
formulations and analysis modes. They are stored (together with additional information) in a
DAEObject.
CircuitEquations (Section 3.5.1, Chapter 2.4, Section 2.4.2, Section 2.6.4) sets up circuit equations
from a Circuit or Netlist object and returns a DAEObject.
Solve (Section 3.5.4, Section 2.4.2) can be used to symbolically solve the equations stored in a
DAEObject.
GetEquations (Section 3.6.5, Section 2.10.2), GetVariables (Section 3.6.7, Section 2.10.2),
GetDesignPoint (Section 3.6.12, Section 2.9.6), and GetParameters (Section 3.6.9, Section 2.10.2)
give easy access to the data stored in a DAEObject.
ApplyDesignPoint (Section 3.6.13), UpdateDesignPoint (Section 3.6.14, Section 2.10.2), and
MatchSymbols (Section 3.6.15, Section 2.9.3) allow for modifying the contents of a DAEObject.
GetDAEOptions (Section 3.6.10) and
SetDAEOptions (Section 3.6.11) allow for accessing or modifying the options stored in a DAEObject.
Statistics (Section 3.6.17, Section 2.9.7) prints information on the complexity of a DAEObject.
Numerical Analyses
The standard numerical circuit analyses can be carried out by the following commands (Chapter 3.7):
NDAESolve (Section 3.7.5, Chapter 2.7) is used to solve nonlinear differential-algebraic equation
systems. It calculates the DC (Section 2.6.6), DC-transfer (Section 2.7.2), and transient solution
(Section 2.7.1), also parametric (Section 2.7.2).
ACAnalysis (Section 3.7.3, Section 2.9.7) computes the small-signal solution of a linear equation
system.
